One of the techniques is to use by products generated from industries while producing various products. Silica fume is also one of the industrial by-products being produced from Ferro silica industries. IT is used in the concrete as supplementary cementitious material rather it is being considered as essential component to produce high performance concrete. This experimental study reports the effect of silica fume as the partial replacement of cement used in mortar. During this study the mortar of thee proportions; l: l, and 1:3 were produced With partial replacement of cement by Silica fume (S.F) being 5% and 10% by weight of total binder. Effect of silica fume is studied in terms of the strength development of mortar. For this purpose the specimens were tested at the ages of Iday, 7day, 28days, 60days and 91days. Super plasticizer (S.P) was added as 1% of the cement/ (binder) by weight to adjust the required workability. Entire the specimens were cured in water up to the age of testing. In addition normal mortar of same proportions without S.F were also cast and tested to compare the results. Results revealed that the mortars With S.F exhibited not only remarkably higher compressive strength at 28 days and later but also unlike the other cementitious materials, high early age strength too.
