The overall production of the cement has greatly increased which results lots of problems in environment as it involves the emission of CO2 gas. Environmental concerns, stemming from the high energy expense and carbon dioxide emission associated with cement manufacture have brought about pressures to reduce cement consumption through the use of supplementary materials. Materials such as Metakaolin have good pozzolanic activity. To achieve sustainability in construction world, number of substitution materials are used. Metakaolin is widely used green pozzolana. Metakaolin is calcined clay (koalite). It is obtained from raw material i.e. Kaolin Clay (very fine, white). There is very little emission of carbon dioxide whiles the production of Metakaolin as compared to cement hence it is called as green pozzolana. The chemical properties of cement were compared with Metakaolin, so that we can replace cement with Metakaolin. It also solve ecological and environmental problems because cheaper production of Metakaolin and more durable. Therefore this paper provides a scope for more research which is required for green and durable concrete.
