Ready Mix Concrete Process

Mastour ReadyMix is a Ready mix Concrete, cement and related construction materials and services company Jeddah Saudi Arabia

Concrete is one of the most versatile, durable, efficient, cost effective construction materials available. With a worldwide production rate of 5 billion cubic tons per year, it is the second most consumed substance on earth after water. The United Arab Emirates (UAE). alone uses about 130 million cubic meters of ready-mixed concrete each year. It is used in highways, streets, parking lots, parking garages, bridges, high-rise buildings, dams, homes, floors, sidewalks, driveways, and numerous other applications.
Concrete has no intrinsic form and its ultimate shape and texture is dictated by the formwork into which it is poured. As a result, finished concrete can assume almost any color, shape or texture. This versatility gives concrete designers and contractors a medium with unlimited potential.
What is the difference between Concrete and Cement ?
People often confuse concrete and cement. Cement is actually an ingredient in concrete that glues together the rock or gravel with the sand, water, and other additives. When a concrete truck is seen driving down the road, it contains ready mixed concrete, meaning a mixture of materials forming concrete.
Is the concrete in sidewalks the same as the concrete in bridges ?
Concrete can be made thousands of different ways. Numerous types sizes and colors of sand, rock, gravel, cements, and chemicals can make today’s concrete do almost anything, from holding up a skyscraper to filling a hole in the ground. Concrete can be made of varying strengths, densities, colors, and characteristics, each serving varying purposes.

Consequently, we possess solid wherewithal & understanding of the technicalities & specific requirements of  Ready mix Concrete that  is to be used for quality & speedy completion of diverse construction projects.

2- AND THE INDUSTRY IS ON THE UPSWING
In most developed countries, such as US and Europe, 75% and 70% respectively of the total cement production is consumed in the form of Ready mix Concrete, due to the several advantages it holds over traditional site-mix concrete. Not only is the quality of the ready mix concrete produced much better than the on-site mix concrete, but even the wastage of the basic materials is eliminated.
With Ready mix Concrete, there is no need for storage space for basic materials at the site, or for procurement / hiring of plant and machinery. Besides minimizing labor requirement, the use of Ready mix Concrete also reduces noise and dust pollution at site and streamlines organization at site.
One of the biggest advantages of Ready mix Concrete use is the massive reduction in the time required for production and delivery. Boosted by these key advantages, the use of Ready mix Concrete  is fast picking up in Saudi Arabia, and Mastour ReadyMix, on the back of its solid experience in this field, is well-positioned to arm clients with high-tech concrete solutions to build and construct mega housing projects, townships, commercial complexes, factories, institutions & universities, bridges, highways, flyovers and railways faster and sturdier.

High Scale Infrastructure

Mastour Ready Mix is a well-established and market leading ready mix concrete producer in Kingdom of Saudi Arabia

We believe that we can make a tremendous difference by helping to build affordable housing and better, more modern, and durable community infrastructure such as roads and sidewalks, schools, hospitals, parks, and other public spaces.
The intelligent use of concrete as a building material can reduce key environmental impacts that contribute to climate change and other significant environmental issues. Concrete’s inherent properties—extreme durability, rigidity, and high reflectivity—make it ideal for large scale infrastructure projects.
When we participate in the development of large scale infrastructure projects, a primary focus is on concrete paving for roads, highways and sidewalks, buildings, schools, hospital, parks, and public spaces.
Concrete pavements, as compared to those built with asphalt, offer the following potential benefits:

• Greater Durability: Since concrete pavements can be designed to last over 40 years, concrete is the best long-term pavement solution.
• Better Traffic Flows: The durability of concrete minimizes the need for extensive repairs or annual maintenance of roads and highways, thereby avoiding traffic problems for their users. When repairs are necessary, they are typically smaller in scope than those for asphalt pavements.
• Reduced Life Cycle Costs: Although the initial investment in concrete pavements is marginally higher than asphalt pavements, concrete pavements require less maintenance over their lifetime, making them the more cost-effective solution.
• Reduced Temperature: Concrete pavements provide reflective surfaces that minimize the “urban heat island” effect.
• Better Light Reflection: Concrete reflects 33 percent to 50 percent more light than asphalt. This is especially important for driving safely at night and for reducing street lighting costs.
• Reduced Rolling Resistance: Due to its rigidity, concrete paving offers significantly less resistance for a vehicle’s wheels to roll. Consequently, concrete paving requires lower fuel consumption for vehicles traveling faster than 30 km/h, compared to a flexible pavement such as asphalt. On any given roadway where concrete is used, the higher the traffic volumes, the greater the savings in fuel consumption.
• Increased Safety: Concrete pavements reduce the probability of road accidents. They not only provide better visibility at night, but also are easily textured during construction to create a surface that provides superior traction and a quiet ride.

Cement

Mastour ReadyMix is a Ready mix Concrete, cement and related construction materials and services company Jeddah Saudi Arabia

Cement is the main basic ingredient of ready-mix concrete. Whether in bags or in bulk, Mastour ReadyMix provides its customers with high-quality branded cement products for their construction needs.
Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement.

Cement is the most widely used construction material worldwide. It provides beneficial as well as desirable properties, such as compressive strength (construction material with highest strength per unit cost), durability, and aesthetics to a variety of construction applications.
Some properties of cement-based products are:
Hydraulic
The hydration reaction between cement and water is unique: the material will set and then harden. Interestingly, the hydraulic nature of the reaction allows hydrated cement to harden even under water.
Aesthetic
Prior to setting and hardening, hydrated cement exhibits plastic behavior. Therefore, it can be cast into molds of different shapes and forms, and can generate aesthetically interesting architectures difficult to achieve with other construction materials.
Durable
When properly used (e.g., good concrete mix design practices), cement can yield structures which have a long service life that withstand extreme changes in weather conditions and chemical attack.
Acoustic
Cement–based material can provide excellent noise insulation with the appropriate design.

About Concrete

Mastour ReadyMix is a Ready mix Concrete, cement and related construction materials and services company Jeddah Saudi Arabia

Concrete is a composite building material made from the combination of aggregate and a binder such as cement. The most common form of concrete is Portland cement concrete, which consists of mineral aggregate (generally gravel and sand), Portland cement and water. After mixing, the cement hydrates and eventually hardens into a stone-like material. When used in the generic sense, this is the material referred to by the term concrete.
For a concrete construction of any size, as concrete has a rather low tensile strength, it is generally strengthened using steel rods. This strengthened concrete is then referred to as reinforced concrete. In order to minimize any air bubbles, that would weaken the structure, a vibrator is used to eliminate any air that has been entrained when the liquid concrete mix is poured around the ironwork. Concrete has been the predominant building material in this modern age due to its longevity, formability, and ease of transport. Recent advancements, such as Insulating concrete forms, combine the concrete forming and other construction steps (installation of insulation). All materials must be taken in required proportions as described in standards.

How Does Concrete Work?

Mastour ReadyMix is a Ready mix Concrete, cement and related construction materials and services company Jeddah Saudi Arabia

Modern concrete consists primarily of four components: Portland cement, sand, gravel and water. A common misconception with concrete is that it dries and gets hard. Actually, the hydraulic cement reacts with the water in a chemical process called hydration. As an example, concrete can be placed underwater and will still change from a liquid state to a solid state and achieve full strength.
Many additional ingredients can be added to the basic concrete mix in order to change the properties of the resulting concrete. The following list shows some common admixtures (additives) and additional ingredients and their basic purposes:

Admixtures

1. Accelerators speed up the hydration, or hardening, of the wet concrete. Often used in colder temperatures so the concrete crew has less waiting time between placing and finishing the concrete.
2. Retarders slow the hydration, or hardening, of the wet concrete. Often used in hotter temperatures so the concrete doesn’t set too quickly, allowing the concrete finishing crew to get the proper finishing work completed.
3. Air entraining agents add and help distribute tiny air bubbles throughout the concrete. These tiny air bubbles help the concrete resist the freeze-thaw cycles with much less cracking and damage.
4. Plasticizers and Super plasticizers improve the workability of the concrete during the wet (or plastic) stage allowing the concrete to flow more easily. They are particularly helpful when placing concrete around congested rebar arrangements. Alternatively, Plasticizers and Super plasticizers can be used to lower the water content in the concrete while keeping a decent level of workability.
5. Pigments change the color of the concrete for aesthetic reasons.

Additions

1. Fly Ash can replace about half of the required amount of Portland cement. Fly Ash is a by product of coal fired electric generating plants, so is often readily available and economical. Concrete made with Fly Ash and Portland cement can have higher strength and improved chemical resistance and durability. The use of Fly Ash concrete is considered environmentally sound, since most fly ash otherwise ends up in landfills and the energy to produce the replaced Portland cement can also be saved.
2. Ground granulated blast furnace slag (GGBS or GGBFS) can also replace part of the required Portland cement. GGBS is a by product  of the steel production process. GGBS has had the most use in Europe and Asia.
3. Silica Fume can also replace part of the required Portland cement. Silica Fume is a by product of the manufacture of silica alloys. The particle size of Silica Fume is 100 times smaller than that of Portland cement. Silica Fume improves concrete strength, abrasion resistance and corrosion resistance to chemicals, particularly to salts.

Material Testing and Quality Control Department

Material Testing and Quality Control Department 

At Mastour Ready Mix, we understand that our concrete and cement products, are the most unique and versatile building materials in the world/gulf/saudi. It can assume virtually any shape and reach great strengths. Concrete is ideal for any building project such as residential homes, schools, high-rise buildings, bridges, dams, highways etc. Concrete is perishable in its plastic state and very “sensitive” from the time the raw materials are combined to the final product. Mixing, transportation, placing, and curing can influence its plastic and hardened properties. This is why Mastou Ready Mix places great emphasis on quality by expanding the parameters of its concrete quality management model from quality control to quality assurance. Mastou Ready Mix is leading the way to higher quality practices with the implementation of a Quality Management System based on the guidelines and principles

The company has plants and water purification device examining the ratio of salts (TDS ) Where the water purification process and to ensure compliance with the U.S.A standards, is an important factor to achieve the highest quality of concrete.

Technical recommendations

Should follow the recommendations of engineering during the casting: -

• On the client, to make every effort to unload the concrete from the truck mixer as soon as possible, in terms of time factor is very important for the quality of concrete.
• During the concrete pouring, especially in columns, ceilings and cabinets recommends using vibrators to avoid honeycomb and to removed air voids to maintain the concrete quality and shape.
• We recommend using good wood, especially for the columns in order to maintain the quality of the concrete and shape.
• We recommend that the request for additional water to the mixture at site is prohibited, any additional water at site adversely affect the quality of concrete.

Recommendations of the ready-mixed concrete after casting :- Moisture must be maintained during the process of curing of concrete after casting so as not to loss moisture rapidly as the rapid loss of moisture during hardening will result in no doubt surface cracks. We recommend treatment with wet burlap or work pools of water with sand barriers to keep the water as long as possible.
Concrete recommendations to address backlog of doubt :- We recommend that you keep the surface moist at all times and can be delayed doubt concrete for several hours and that was the result of the chemical additives for concrete, which in turn delayed doubt concrete for several hours. We recommend that you deal with concrete containing Microsilica

Concrete Block

Mastour ReadyMix is a Ready mix concrete and cement products company Jeddah Saudi Arabia,

Concrete block, cement block, and foundation block – is a large rectangular brick used in construction. Concrete blocks are made from cast concrete, i.e. Portland cement and aggregate, usually sand and fine gravel for high-density blocks. Lower density blocks may use industrial wastes as an aggregate. Clinker blocks use clinker as aggregate. In non-technical usage, the terms cinder block and breeze block are often generalized to cover all of these varieties. Lightweight blocks can also be produced using aerated concrete

Uses

Concrete block, when built in tandem with concrete columns and tie beams and reinforced with rebar, is a very common building material for the load-bearing walls of buildings, in what is termed “concrete block structure” construction. Large buildings typically use copious amounts of concrete block; for even larger buildings, concrete block supplements steel I-beams. Tilt-wall construction, however, is replacing Concrete Block Structure for some large structures.

Parking Stoppers

Mastour Ready Mix provides its customers with high-quality branded cement products for their construction needs

A parking space commonly contains a parking Stoppers, a barrier which is used to prevent cars from pulling too far into the space and obstructing a neighboring parking space, curb, or sidewalk.
This barrier, also called a Parking Stoppers, is usually made of concrete  and will normally be a horizontal bar to stop the tires from moving forward or a vertical bar that may cause damage to the vehicle if contact is made. In a parking garage, the barrier will often be a concrete wall.
All of our Parking Stoppers have a smooth form finish. The stops are vibrated as they are cast to provide good consolidation of the concrete which increases durability and improves their appearance. Holes are formed through the tops of the curbs at each end of the piece so that a ½” thick piece of rebar can be inserted for anchoring to asphalt or concrete surfaces. You can be sure that when you buy from us, you are buying a strong, durable product that you deserve. Don’t spend good money on cheap imitation parking stoppers, put your hard earned money in a quality product.

Using Ready Mix Concrete in Construction

Mastou Ready Mix, we understand that our ready mix concrete and cement products, are the most unique and versatile building materials.

Building a house or any other type of building is not easy, especially when you do it from scratch. However, there are some shortcuts you can use when you want to shorten the building time and have your project ready in time. One of them involves the use of ready-mix concrete. This is a type of concrete that is manufactured in a factory or batching plant, according to a set recipe, and then delivered to a work site, by truck mounted transit mixers. The result is a precise mixture, allowing specialty concrete mixtures to be developed and implemented on construction sites. Of course, there are some advantages that this type of concrete offers

We were able to say that this was the most commonly used form of concrete. One of the most important advantages when using ready-mix concrete is the fact that you get to save time. As you probably know, time is usually the most important resource. Using ready-mix concrete speeds up the entire process.

Another advantage of using ready-made concrete is the high-quality of the concrete. Ready-mix concrete is consistently of a higher quality than concrete mixed on site. In other words, you’ll get high-quality concrete and you’ll save time and man power at the same time. Just to help you get an idea, you should know that mixing plants use natural ingredients and the standard recipes call for 10 percent to 15 percent cement, which is made up of clay, limestone, sand or shale; about 60 percent to 70 per cent aggregates, typically rock and gravel; and 20 per cent water.

The use of ready-mix concrete also reduces pollution outputs from construction sites, such as the dust created when mixing concrete on site and the possibility of unnecessary wastage due to making more than you need. Although ready-mix concrete requires special care and precautions during casting otherwise it could cause cracks and failure. More information’s about ready mix concrete Products and Services.

Hidden benefits of Ready Mix Concrete

Mastour ReadyMix is one of the most efficient ready-mix concrete producers in the K.S.A.

Ready mix concrete is generally looked upon as a costly product rather than as a facility for an appropriate quality product on site as and when required. Ready Mix Concrete is considered to be more expensive compared to site mixed concrete. The initial cost of Ready Mix Concrete may seem higher. However, Ready Mix Concrete has several hidden advantages that can substantially reduce cost to the owner. And since these cannot be accurately determined, they are often ignored while evaluating the cost of RMC over site mixed/produced concrete.
The advantages over the site-mixed concrete are–the quality of concrete will be superior over the site-mixed concrete. However, it will greatly depend on the controls and checks exercised at site and at Ready Mix Concrete producer’s plant. The considerable wastage of materials on site due to poor storage conditions and repeated shifting of the mixer location is prevented.
In most cities, the plot area is barely sufficient to store reinforcement steel, concrete and other construction materials. Using Ready Mix Concrete can cause less congestion and better housekeeping on the site resulting in efficient working environment. Obtaining Ready Mix Concrete at site can reduce supervision and labor costs, which would otherwise be required for batching and mixing of concrete at site.
The modern RMC plants have an automatic arrangement to measure surface moisture on aggregates. This greatly helps in controlling the water to cement ratio (w/c), which results in correct strength and durability. Due to automation process the control and check can be emphasized at each and every stage of RMC manufacturing and thus ensuring better and consistent quality batch after batch. RMC encourages mechanization and promotes the use of new materials like micro silica and fibers that can be safely used in ready mix concrete, which in conventional concrete may pose problems

Precast Concrete Floors

Mastour Ready Mix is a well-established and market leading ready mix concrete producer in Jeddah Kingdom of Saudi Arabia

The vast majority of new homes have solid concrete ground floors. This is excellent from the point of view of sound
reduction. However, upstairs floors are probably the greatest single source of noise in homes. With many homeowners
moving   away  from carpet finishes   to    timber   floors ,   t h e  problem has increased significantly. Impact noise through timber floors can be a significant source of irritation, especially
when children are playing with friends in their bedroom. Tests show the airborne sound insulation of a concrete floor to be in the order of 47 to 52 decibels. A standard timber joist floor in
a comparative test has a rating of only 30 to 38 decibels. The substantial performance difference has encouraged many self builders to use precast concrete first floors. Those who do will enjoy the comfort of a quieter, safer home.
Tests have shown the airborne sound insulation of a concrete upstairs floor to be in the order of 47to 52 decibels. A
standard timber floor in a comparative test has a rating of 30 to 38 decibels.

Fire Safe Concrete

Mastour ReadyMix is a Ready mix concrete and cement products company Jeddah Saudi Arabia

The safety of your family is a primary consideration when purchasing a new home.Concrete homes have a  much higher level of fire safety than lightweight framed homes,with 4 times longer fire resistance – effectively 2 hours protection compared with 30minutes for lightweight timber of steel frame construction. Concrete is an incombustible material and it will not produce smoke or in any way add to the fire. Fires which occur in concrete built homes will burn at a lower temperature, the house will retain its structural stability and the structure of the building will almost always remain completely intact. The same cannot be said of lightweight framed homes, where the structural elements become part of the fire, produce higher temperatures and higher smoke levels and the building is frequently completely destroyed, requiring demolition. If you are buying an apartment which is built using lightweight framed construction – check the cost of the insurance premium. Some leading Irish Insurers will not ensure lightweight framed buildings above two storeys in height

Advantages of Ready Mix Concrete

Mastour Ready Mix is a well-established and market leading ready mix concrete producer in Kingdom of Saudi Arabia

The ready mix concrete has many advantages compared to the traditional way in producing concrete, these advantages are:
• Accuracy of mix concrete and calibration of the components.
• Accuracy of controlling the quality of the components (cement, aggregates, water and additives).
• Superiority of the mixing process quality due to the absence of the human error.
• Accuracy and the centrality of quality control operations.
• Avoidance of the burden of storing raw materials in site whiles the production of concrete.
• Avoidance of losing the required quality of raw materials due to poor setting and storing or due to weathering.
• Reduction of the labor required for the work of mixing and pouring.
• Easiness of pumping concrete in high-rise.
• Easiness of concrete surface serving & leveling.
• Reduction and time saving of site works duration.
• Reduction of waste of raw materials resulting from poor concrete mixing workmanship and poor setting and storing.

Concrete Barrier

Mastour ReadyMix is a Ready mix concrete and cement products company Jeddah Saudi Arabia,

Modular Concrete Barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing crossover in the case of head-on accidents.
Also utilized extensively to re-route traffic and protect pedestrians during highway construction, such barriers are increasingly deployed in anti-terrorism roles as both quick fixes and semi-permanent protections against perceived land borne threats.
Their widespread use in road construction has led to wide application as a generic, portable barrier during general construction projects and temporary re-routing of traffic into stopgap carpool and rush hour reversing highway lanes.
Our concrete barriers are available in different sizes . They are ideal for many uses including; temporary roadblocks, protecting vacant sites, Bridge Approaches and Railings, Highway hazards such curve, perimeter fencing, channeling traffic, concrete security blocks and earth retention. Our concrete barriers can be painted with warning signs, company branding, or logos.

Cement

Mastour ReadyMix is a Ready mix concrete and cement products company Jeddah Saudi Arabia

In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. modern concrete that was made from crushed rock with burnt lime as binder. The volcanic ash and pulverized brick additives that were added to the burnt lime to obtain a hydraulic binder .
Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions that occur independently of the mixture’s water content; they can harden even underwater or when constantly exposed to wet weather. The chemical reaction that results when the anhydrous cement powder is mixed with water produces hydrates that are not water-soluble. Non-hydraulic cements (e.g. gypsum plaster) must be kept dry in order to retain their strength.
The most important use of cement is the production of mortar and concrete—the bonding of natural or artificial aggregates to form a strong building material that is durable in the face of normal environmental effects.
Concrete should not be confused with cement, because the term cement refers to the material used to bind the aggregate materials of concrete. Concrete is a combination of a cement and aggregate.

Concrete mixer

Mastour Ready Mix is one of the major companies operating in the field of construction and reconstruction depends in its work

A concrete mixer (also commonly called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens. An alternative to a machine is mixing concrete or cement by hand. This is usually done in a wheelbarrow; however, several companies have recently begun to sell modified tarps for this purpose.
Industrial Mixers
Today’s market increasingly requires consistent homogeneity and short mixing times for the industrial production of ready-mix concrete, and more so for precast concrete. This has resulted in refinement of mixing technologies for concrete production. Different styles of stationary mixers have been developed, each with its own inherent strengths targeting different parts of the concrete production market. The most common mixers used today fall into 3 categories: Twin-shaft mixers, Vertical axis mixers

Stamped Concrete

Stamped Concrete Products in various patterns are also available at Mastour ReadyMix can be customized and proportioned to fit your specific needs and application.

Stamped Concrete is concrete that is patterned and/or textured or embossed to resemble brick, slate, flagstone, stone, tile, wood, and various other patterns and textures. Stamped concrete is commonly used for patios, sidewalks, driveways, pool decks, and interior flooring. The ability of stamped concrete to resemble other building materials makes stamped concrete a less expensive alternative to using those other authentic materials such as stone, slate or brick.
There are three procedures used in stamped concrete which separate it from other concrete procedures; the addition of a base color, the addition of an accent color, and stamping a pattern into the concrete. These three procedures provide stamped concrete with a color and shape similar to the natural building material. It also is longer lasting than paved stone, and still resembles the look.

Procedures

Adding base color

The base color is the primary color used in stamped concrete. The base color is chosen to reflect the color of the natural building material. The base color is produced by adding a color hardener to the concrete. Color hardener is a powder pigment used to dye the concrete.
The color hardener can be applied using one of two procedures; integral color or cast-on color. Integral color is the procedure where the entire volume of concrete is dyed the base color. The entire volume of concrete is colored by adding the color hardener to the concrete truck, and allowing all the concrete in the truck to be dyed. Cast-on color is the procedure where the surface of the concrete is dyed the base color. The surface of the concrete is colored by spreading the color hardener onto the surface of the wet concrete and floating the powder into the top layer of the wet concrete.
Concrete can be colored in many ways; color hardener, integral liquid or powder, acid stains to name a few. The process of integrally coloring the concrete offers the advantage of the entire volume being colored; however, the surface strength is not increased as with the use of color hardener. Dry shake color hardener is another popular way to color concrete. You broadcast the hardener on the concrete as soon as it is floated for the first time. After letting the bleed water soak into the hardener you float and trowel it in. This method only covers the surface about 3/16 of an inch but it gives the concrete surface a longer wear life.

Adding accent color

The accent color is the secondary color used in stamped concrete. The secondary color is used to produce texture and show additional building materials (e.g. grout) in the stamped concrete. The accent color is produced by applying color release to the concrete. Color release has two purposes. Color release is a pigment used to color the concrete and color release is a non-adhesive used to prevent the concrete stamps from sticking to the concrete.
The color release can be applied in one of two procedures based on the two forms it is manufactured in: powdered (cast-on color release made up of calcium-releasing powders that repel water); or liquid – which is a light aromatic-based solvent, spray-on color release. Cast-on color release is a procedure where the powder color release is applied by spreading the color release on the surface of the concrete before the concrete is stamped. Spray-on color release is a procedure where liquid color release is sprayed on the bottom of the concrete stamps before the concrete is stamped.

Stamping patterns

The pattern is the shape of the surface of the stamped concrete. The pattern reflects the shape of the natural building material. The pattern is made by imprinting the concrete shortly after it has been poured with a “concrete stamp“. Most modern concrete stamps are made of polyurethane, but older “cookie cutter” style stamps were made of various metals. The old style stamps lacked the capabilities of forming natural stone texture.
Concrete stamping is the procedure which uses the concrete stamps to make the pattern in the stamped concrete. Concrete stamps are placed on the concrete after the color release has been applied. The concrete stamps are pushed into the concrete and then removed to leave the pattern in the stamped concrete.
In most cases concrete stamping is made to look like ordinary building products. Whether it be flagstone, brick, natural stone or any other common exterior looks, but there are many ways to personalize your own kind of stamp. It could be a homemade stamp or a recycled stamp, you can be as basic or as ornate as you wish. The Process is easy, first find a design that you, the homeowner, or contractor thinks will be a good fit. After making a mold of the desired stamp design, plan out the way it will look and fit in your designated area. The hardest part of stamping is the waiting, you must make sure the concrete is hard enough that the stamp won’t sink but loose enough that it will make a clean stamp. Do not be afraid of trying new and creative stamps around your house. However, remember to be sure to test the stamp on a demo before stamping onto the permanent surface.

History

Stamping concrete increased in popularity in the 1970s when it was first introduced in the World of Concrete. Builders saw it as a new way to satisfy the customer and make their budget work simultaneously. This technique of stamping concrete has been done since at least the 1950s. When stamping concrete first began, there were very few choices of design and colors. However, as the industry grew more stamping patterns were being created along with many different types of stains to give us the vibrant colors we have today. Another advantage to using stamped concrete, is that it can be applied to many different surfaces and textures. Such as driveways, highways, patios, decks, and even floors inside the home.

Concrete is one of the most durable building materials. It provides superior fire resistance, compared with wooden construction and can gain strength over time. Structures made of concrete can have a long service life. Concrete is the most widely used construction material in the world with annual consumption estimated at between 21 and 31 billion tones.
Concrete is used more than any other man-made material in the world. As of 2006, about 7.5 billion cubic meters of concrete are made each year—more than one cubic meter for every person on Earth.
Energy efficiency
Energy requirements for transportation of concrete are low because it is produced locally from local resources, typically manufactured within 100 kilometers of the job site. Similarly, relatively little energy is used in producing and combining the raw materials (although large amounts of CO2 are produced by the chemical reactions in cement manufacture). The overall embodied energy of concrete is therefore lower than for most structural materials other than wood.
Once in place, concrete offers significant energy efficiency over the lifetime of a building. Concrete walls leak air far less than those made of wood-frames. Air leakage accounts for a large percentage of energy loss from a home.
Pervious concrete
Pervious concrete is a mix of specially graded coarse aggregate, cement, water and little-to-no fine aggregates. This concrete is also known as “no-fines” or porous concrete. Mixing the ingredients in a carefully controlled process creates a paste that coats and bonds the aggregate particles. The hardened concrete contains interconnected air voids totaling approximately 15 to 25 percent. Water runs through the voids in the pavement to the soil underneath. Air entrainment admixtures are often used in freeze-thaw climates to minimize the possibility of frost damage.
Fire safety
Concrete buildings are more resistant to fire than those constructed using wood or steel frames, since concrete does not burn. Concrete reduces the risk of structural collapse and is an effective fire shield, providing safe means of escape for occupants and protection for fire fighters.
Options for non-combustible construction include floors, ceilings and roofs made of cast-in-place and hollow-core precast concrete. For walls, concrete masonry technology and Insulating Concrete Forms (ICFs) are additional options. ICFs are hollow blocks or panels made of fire-proof insulating foam that are stacked to form the shape of the walls of a building and then filled with reinforced concrete to create the structure.
Concrete also provides the best resistance of any building material to high winds, hurricanes, tornadoes due to its lateral stiffness that results in minimal horizontal movement.
Earthquake safety
As discussed above, concrete is very strong in compression, but weak in tension. Larger earthquakes can generate very large shear loads on structures. These shear loads subject the structure to both tension and compression loads. Concrete structures without reinforcing, like other unreinforced masonry structures, can fail during severe earthquake shaking. Unreinforced masonry structures constitute one of the largest earthquake risks globally. These risks can be reduced through seismic retrofitting of at-risk buildings.

The word Concrete comes from the Latin word “concretus” (meaning compact or condensed), the perfect passive participle of “concrescere”, from “con-” (together) and “crescere” (to grow).
Concrete was used for construction in many ancient structures.
Concrete is a composite construction material composed primarily of aggregate, cement and water. There are many formulations that have varied properties. The aggregate is generally a coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate such as sand. The cement, commonly Portland cement, and other cementitious materials such as fly ash and slag cement, serve as a binder for the aggregate. Various chemical admixtures are also added to achieve varied properties. Water is then mixed with this dry composite which enables it to be shaped (typically poured) and then solidified and hardened into rock-hard strength through a chemical process known as hydration. The water reacts with the cement which bonds the other components together, eventually creating a robust stone-like material. Concrete has relatively high compressive strength, but much lower tensile strength. For this reason is usually reinforced with materials that are strong in tension (often steel). Concrete can be damaged by many processes, such as the freezing of trapped water.
Concrete is widely used for making architectural structures, foundations, brick/block walls, pavements, bridges/overpasses, motorways/roads, runways, parking structures, dams, pools/reservoirs, pipes, footings for gates, fences and poles and even boats. Famous concrete structures include the Burj Khalifa (world’s tallest building).
Use of concrete became scarce until the technology was re-pioneered in the mid-18th century.
The environmental impact of concrete is a complex mixture of not entirely negative effects; while concrete is a major contributor to greenhouse gas emissions, recycling of concrete is increasingly common in structures that have reached the end of their life. Structures made of concrete can have a long service life. As concrete has a high thermal mass and very low permeability, it can make for energy efficient housing.
