This project is related on the use of Silica fume as a substitution of cement and 100% m- sand as fine aggregate. Concrete is the most widely utilized material in the construction industry and will hold good for years. The credit is attributed to the properties of concrete like excellent strength, durability and less maintenance costs. But in the recent years, the concrete industry is facing a big challenge mainly due to the cement which is a vital component.In order to improve the durability properties many types of special concretes such as High Strength Concrete, High Performance Concrete, Fibre Reinforced Concrete, Self-Compacting Concrete, etc. have been developed. High performance concrete has become an attractive option to Civil Engineers due to the special characteristics like early strength, ease of placement, permeability, mechanical and durability properties. The performance of High strength Concrete (HSC) is enhanced by the addition of admixtures which act as pozzolans as well as fillers, thereby improving the microstructure of the interfacial transition zone making it denser and impermeable. Silica Fume (SF) is a commonly used pozzolanic material owing to its high silicon dioxide content and fineness. This ultra fine property of SF used in concrete to improve its strength and durability.
