ABSTRACT : The aim of this study is to evaluate the performance of S.F (S.F), as a admixture in Concrete. The S.F (S.F), industrial by product found to be an attractive cementations material which is by product of smelting process in the silicon and ferrosilicon industry. The Partial replacement of S.F (S.F), and its effects on Concrete properties has been studies by adopting M-25Concrete mix in this dissertation. The main parameter investigated in this study M- 25Concrete mix with Partial replacement by S.F (S.F), with varying 0, % 10%, 20 % and 30 % by weight of cement. The Chart presents a detailed experimental study on compressive strength for 7, 28, 56 days respectively. The result of experimental investigation indicates that the use of Silica Fume (S.F), in Concrete has increased the strength and durability at all age when compared to normal Concrete. Hence the use of S.F (S.F), leads to reduction in cement quantity for construction purpose and its use should be promoted for better performance as well as for environmental sustainability. Keywords: M25, silica fume, compressive strength, split tensile strength, flexural strength, etc,. I.INTRODUCTION During the last three decades, great strides have been taken in improving the performance of concrete as a construction material. Particularly Silica Fume (SF) and fly ash individually or in combination are indispensable in production of high strength concrete for practical application. The use of silica fume as a pozzolana has increased worldwide attention over the recent years because when properly used it as certain percent, it can enhance various properties of concrete both in the fresh as well as in hardened states like cohesiveness, strength, permeability and IMPROVEMENT OF CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH SILICA FUME (S.F) POTHULA RAJESH 1 and K.VAMSI KRISHNA 2 1 PG Student, Structural Engineering, Department of Civil Engineering, Malla Reddy Engineering College (Autonomous), Maisammaguda, Dhulapally (Post, Via.
