Experimental Examination on Blended Concrete by Incorporating Fly ash and Silica Fume

Abstract

Now days, concrete mixture contains additional cementitious material which imparts additional strength. The admixtures and pozzolanic materials are produced large tons from the fast growth of industries, which is used for this material such as Fly ash, Silica fume, GGBS, copper slag, etc. By using these types of materials improve the concrete dressed in fresh and hardened states. In this present work different tests are held to have tentative results for comparison of conventional concrete including various possessions of concrete mixes developed by using OPC 53 grade cement. These mixes are improved by replacing 5%, 8%, and 10% Silica Fume. After best results of Silica Fume, it is intermingled with Fly Ash with 10%, 22%, 10%, by varying the cement content to 75%, 70%, and 80% in terms of volume. Properties like compressive, split tensile and bending strength are studied for 7, 28 and 56 days.
