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

Laboratory materials

Different quality tests for Ready mix concrete depending on the time of testing
Tests done before delivery: – such as the test (SLUMP TEST) by which the test in coherence of concrete mix where to take a sample from the truck before delivery and is measured by the degree of decline in concrete as shown in Figure.
Tests after the mortar : – After the arrival of concrete to the delivery location, sample was being made to make sure that it in in compliance with the specifications required by client from 15mpa to 100mpa. , According to American standards – British – Saudi Arabia, as well as the American Concrete Institute through cubes or cylinders which are cured and will be tested after 7 days and 28 days, as I have a company mobile laboratory, issued full reports and statistical analysis to verify the specifications and mix design already installed, also verify the quality of the concrete at the site after 7 days and 28 days through a variety of tests conducted at the site and mention some of them for example.
*Hammer Test.
*Test section (coring Test)

Raw materials used

The company produce ready-mixed concrete on the best materials available.

Cement

*OPC Portland cement according to the specifications of America.
*Sulfate Resistant Cement is resistant to the attack of salts, according to the specifications of America.
*Pozollan Portland Cement by American standards.

Graded gravel

basalt rock is extracted harsh clean by bombing and that is crack by refracting a primary and secondary cracking Assistant (mill) then Separation of materials through Screen multiple production in different sizes (3/8”, ¾”, ½”.1” ) by

American standards.

Sand : – Sand mechanically screened to produce clean sand and free from silt, shall be subject to laboratory tests to ensure its compliance Specifications for the U.S. A .

Additional materials

Based on the effort required by the client and the mix design that is prepared in our laboratories, some of which require addition of chemical, and to mention some of them: – .Colored concrete floor for the addition of chemical dyes, iron oxide and (IRON OXIDE) in different colors Use (MICROSILICA) and that of the tanks, swimming pools, concrete, marine and that what is known
(Water Proof)
Article RETARDER) so as to delay the setting time of the concrete.
Article SUPERPLASTICIZER add this article on the effort required from the client.
Materials parallel STABILIZER.
Article ( HIGH RANGE WATER REDUCER) .
Material added to the concrete used in the sea (CORROSION INHIBITOR )
There are also special specifications and special chemicals for concrete fiber and heavy weight concrete .

cooling system

company has a cooling system consists of chiller to cool the water to 8 degrees Celsius, ice plant is also available at the company’s plant, covers factory production of ready-mixed concrete to reduce the temperature of the concrete, especially during hot weather. (summer).

Water purification plants

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
