COMPARISON OF REBOUND NUMBERS FOR M20 CONCRETE WITH SILICA FUME

S.S.Kumar, T.Anitha

Abstract: The concrete is one of the most important for all the construction work. The main role of the concrete based on cement, steel. To improve the strength and durable of the concrete to add the admixture. Silica fume is added to the fresh concrete to improve the durability, ductility and strengthen of the concrete. Because, the silicon dioxide with carbon it which gives silica and carbon monoxide. It is very good permeability and also abrasion resistance. For this present study M20 grade of concrete shall be designed, partial replacement of cement with silica fume will be incorporating the strength for varying percentage ,such as 0%, 5%, 10%, 15%, 20% by weight of cement with rebound hammer value Vs compressive strength.

Keywords: Ordinary Portland cement, Micro silica, compressive strength, tensile strength, Flexural strength
