The increased environmental awareness and its potential hazardous effects, utilization of industrial byproducts has become an attractive alternative to disposal. Silica fume(SF), which is byproduct of the melting process in the silicon and ferrosilicon industry. Silica fume is very effective in the design and development of high performance concrete. This paper presents the results of an experimental investigations carried out to find the suitability of silica fume in concrete. The water binder ratio (W/B) adopted was 0.43. The main parameter investigated in this study is M30 grade concrete by partial replacement of cement with silica fume by 2, 4, 6,8 sand by 10%. .Specimens such as cubes and cylinders were cast for various mix proportions and tested at the age of 14and 28 days. The investigation revealed that the partial replacement of cement by silica fume will develop compressive strength and split tensile strength sufficient for construction purposes The optimum dosage of silica fume found to be 8% (by weight), when used as partial replacement of ordinary Portland cement .Its use will lead to a reduction in cement quantity required for construction purposes and hence sustainability in the construction industry as well as economic construction.
