Supplementary cementitious materials (SCM), silica fume , metakaolin, A75Abstract
Concrete a composite material made from cement, water, fine aggregate and coarse aggregate. The
worldwide production of cement has greatly increased since 1990. Production of cement results in a lot of environmental
pollution as it involves the emission of CO2 gas. Supplementary cementitious materials (SCM) are finely ground solid
materials that are used to replace a portion of the cement in a concrete mixture. But present researchers are in interest
of finding new cement materials by waste materials or waste products produced from industries which are harmful to
environment. The aim of study is partial replacement of cement with A75(silica fume metakaolin) and determine the
compressive strengths for all mixes at the age levels of 24 hours , 7 days and 28 days. Besides the compressive strengths
other properties like compaction factor, slump and water absorption of concrete are determined for five mixes of
concrete. The other test for beam and cylinder also should be noted and compare the split tensile strength and flexural
strength results.
