Investigation on Concrete with M-Sand and Silica Fume

Abstract

The global construction industry uses a significant amount of concrete. In India, the ordinary concrete is created utilizing natural sand from river beds as fine aggregate. Because dwindling natural resources constitute an environmental risk, government restrictions on sand mining have led to a shortage and a sharp rise in the price of the material. The optimization of M-Sand with silica fume as a partial replacement for natural sand is discussed in this work. Compressive and split tensile strengths of concrete mixtures were assessed. Natural sand was substituted with manufactured sand in five proportions of 0, 10, 20, 30 and 40%, while silica fume was substituted for standard Portland cement in amounts of 0, 5, 7.5 and 12.5%. The findings showed that concrete with 30% M-Sand and 7.5% silica fume has increased compressive and split tensile strength.
