Concrete is the most widely used man made construction material in
the world, and is second only water as the most utilized substance on
planet. It is obtained by mixing cementitious materials, water and
aggregates (and sometimes admixtures) in required proportions. The
mixture when placed in forms and allowed to cure, hardens into a
rock-like mass know as concrete. The hardening is caused by chemical
reaction between water and cement and it continues for a long time, and
consequently concrete grows stronger with age. The hardened concrete may
also be considered as an artificial stone in which the voids of larger
particles (coarse aggregate) are filled by the smaller particles ( fine
aggregate) and the voids of fine aggregate are filled with cement. In a
concrete mix the cementitious material and water form a paste called cement-water paste
which in addition to filling the voids of fine aggregates , coast the
surface of fine and coarse aggregates and binds them together as it
cures, thereby cementing the particles of the aggregates together in a
compact mass.
The strength, durability and other characteristics of concrete depend
upon the properties of its ingredients, on proportion of mix, the
method of compaction and other control during placing, compaction and
curing. The popularity of concrete is due to the fact that from the
common ingredients, it is possible to tailor the properties of concrete
to meet demands of any particular situation. The advance in concrete
technology have paved the way to make the best use of local
availability materials by judicious mix proportioning and proper
workmanship, so as the produce concrete satisfying performance
requirement.
The key to producing a strong , durable and uniform concrete, i.e.
high performance concrete lies in the careful control of its basic and
process components .
