AN EXPERIMENTAL STUDY ON STRENGTH PROPERTIES OF CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT WITH FLY ASH, FINE AGGREGATE WITH VERMUCILITE AND SILICA FUME AS MINERAL ADMIXTURE

Concrete is the most common building material for its inherent and unique properties like compressive strength and durability. Upon continuous utilization of the concrete, the raw materials like fine aggregates and coarse aggregates are being extinct. In order to counter this problem, many researchers are being carried out with replacement of various materials. Vermiculate is a light weight material which is being used for thermal resistance in cavity walls is proposed to be one of the alternative sources for fine aggregate. In the present project, Silica fume is added at 5%, 7.5%, 10%, 12.5% and fly ash is partially replaced with cement at 10%, 15%, 20%, then the optimum mix is determined and then vermiculate is replaced with fine aggregate at 5%, 10%, 15%, 20%, 25%, 30% and the test results of compressive strength and tensile strength are compared with conventional concrete for M30 grade concrete.
