Abstract

Owing to growing construction needed for increasing developmental activities massive burden is being posed to the environment in terms of direct products and by products. Cement is prime construction material and its huge production to meet out the demand is of great concern for environmentalists. During the production of cement various harmful gases are emitted out of which CO₂ is of prime concern. Several materials viz. fly ash, rice husk ash, GGBS, silica fume, metakaolin etc. can be used as partial replacement of cement in construction. The use of Supplementary cementitious materials in construction not only improve the mechanical property of cement matrix but also reduce the burden from environment. In this paper an attempt is made to explore the possibility of use of different materials as partial replacement of cement in construction.
