Abstract

Concrete is the most widely used man made construction material. It is obtained by mixing cement, water and aggregates in required proportions. The strength, durability and other characteristics of concrete depend upon the properties of its ingredients on the proportions of mix, the method of compaction and other controls during placing, compaction and curing. In this experiment it is proposed to replace cement by silica fume up to 35 percentage. Silica fume, also known as micro silica, is a fine-grain, thin, and very high surface area silica. Silica fume is a by product in the reduction of high-purity quartz with coke in electric arc furnaces in the production of silicon and ferrosilicon alloys Silica fume is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. Initial tests are conducted for the components of concrete such as cement, fine aggregate and course aggregate. The concrete is mixed as per the mix design that have been derived according to the IS specification. In this experimental study the cement is replaced by Silica fume for various proportions in M20mix concrete and this concrete mix are casted and tested for its compressive strength for cube and Split tensile strength for cylinder is noted for 7 days and 28 days for different proportions.
