Abstract

Massive construction demand in today's world poses a significant threat to the environment owing to the bulk utilization of cement (as a binder material). Cement tends to be an important ingredient for producing qualitative concrete; on the contrary, higher production of cement may lead to high emission of CO₂ gas, which itself is a great concern for the environment as well as society. In order to overcome this issue, several researches have been carried out to reduce the percentage usage of cement in concrete through partial replacement using supplementary cementitious materials, like fly ash, rice husk ash, GGBS, silica fume, metakaolin, etc. The utilization of such materials not only enhances the mechanical properties of the cement matrix but also decreases the burden on the environment. In this article, an attempt has been made to identify the feasible use of different binding materials as a partial replacement of cement in producing concrete.
