Abstract— Use supplementary cementitious material is need of civil industry, because supplementary cementitious material (SCM) becomes essential part of high performance & high strength concrete mix design. These materials may be industrial waste, naturally available, by-product or manufactured consuming less energy. Some of widely used supplementary materials are fly ash(FA), bagasse ash(BA),rise husk ash(RHA), silica fume, granulated blast furnace slag(GGBS), metakaolin(MK), etc. Metakaolin is obtained from calcination of kaolinite between 650° – 800°c. The kaolin is transformed to an amorphous phase which is metakaolin. It has been widely used as a pozzolanic material in mortar and concrete. This paper overview of work carried out on the use of metakaolin as a partial replacement to cement in mortar and concrete.
