NO SOFTWARE USED ONLY EXPERIMENTAL STUDY
The purpose of this study is to find the suitability of Fly Ash and Silica Fume as hybrid admixture replacement materials for cement without compromising the strength & durability of conventional cement based hybrid concrete. Replacement of cement partially by Fly Ash and Silica Fume also reduces the supply demand on cement and may also reduce the emission of CO2 in to atmosphere.
The physical and chemical properties of Fly Ash and Silica Fume has been studied and both the industrial wastes are used to replace the cement at 25%F.A-5%S.F, 20%F.A-10%S.F,15%F.A-15%S.F and 10%F.A-20%S.F. These specimens will be tested for its mechanical properties such as compressive strength, split tensile strength and flexural strength on 7, 28 & 90 days and durability properties like acid attack, sulphate attack, acid attack and water permeability.
After determining the properties of the concrete mixes, the optimum percentage of replacement levels of Fly Ash and Silica Fume will be found out for the optimized concrete Mix.
