Compressive Strength of Concrete by Replacing Cement with Silicafume for M20 Grade

Ratod Vinod Kumar, Koudagani Venkatesh

Abstract: Cement is the back bone for global infrastructure development. It was estimated that global production of cement is about 1.3 billion tonnes in 1996. Production of every ton of cement emits carbon dioxide to the tune of about 0.87 ton. It can be said that 7 % of the worlds carbon dioxide emission is attributable to Portland cement industry. Silica Fume is a very fine powder consisting mainly of spherical particles or microspheres of mean diameter about 0.15 microns, with a very high specific surface area (15, 000-25, 000 m2/kg). To fulfil the objective various properties of concrete using silica fume have been evaluated. Further to determine the optimum replacement percentage comparison between the regular concrete and concrete containing silica fume is done. It has been seen that when cement is replaced by silica fume compressive strength increases up to certain percentage (10 % replacement of cement by silica fume). But higher replacement of cement by silica fume gives lower strength
