Mechanical Strength Development In Concrete

In construction industry, there is an increase in need to get lowest cost or cost effective concrete. At the same time, excessive use of cement content without adequate reason is still common in construction industry. This means there is a need to study and optimize the mix proportion of concrete and use of supplementary cementitious materials in effective way. The most commonly used supplementary cementitious materials are wastes. The use of this industrial waste has technical economical and environmental benefits besides the reduction of carbon-dioxide emission from cement production plants. The behavior of concrete should be good in both fresh state and hardened state. This means to say that at fresh stage, it should be workable, have an ease in transport and placement without chances of segregation, instead, homogeneous. At hardened stage, it should have desired strength, primarily the compressive strength and durability as well.
