Study on Characteristics Compressive Strength of High Strength Concrete Using Silica Fume

Abstract

The Strength and performance of concrete plays a vital for construction of heavy structures like bridges, power stations, tall buildings, etc. Concrete that meets special performance and uniformity requirements are produced by using different mix proportions, different curing practices, using different admixtures and by using low water cement ratio. These concretes contain new type of Superplastiser which responsible for obtaining high strength and high durability. In addition to High Performance Concrete which has become relatively common, some High Strength Concrete, which is of interest for the Indian market. For high strength concrete the characteristic compressive strength varies between 40MPa and 100MPa.The alternate materials available to increase the strength of concrete are silica fume, metakaolin, alccofine, Ground Granulated Blast furnace Slag (GGBS), etc. So in this study silica fume is partially replaced with 10%, 20% and 30% of cement with constant percentage of superplastiser as 1.5% and compression test is carried out.
