Mix Proportion of Cementitious material in pervious concrete

Abstract

Now a days the concrete industry is constantly looking for supplementary cementious material with the objective of reducing the solid waste disposal problem and economic in cost. The Fly ash and Ground granulated blast furnace slag (GGBS) are among the solid wastes generated by Thermal power plant and iron manufacturing industry. To overcome from this crisis, partial replacement of cement with Fly ash and GGBS can be an economic alternative. And the cement is partially replaced with Fly ash and GGBS by 10%, 20% up to 30%. The effect of paste density on properties of pervious concrete by addition of various cementitious admixtures such as Fly ash and Ground Granulated blast furnace Slag (GGBS). So the physical and mechanical properties of pervious concrete will be beneficial for the forthcoming use of Fly ash and GGBS in the construction field of pervious concrete which will lead to reduce the cement consumption, environmental issue and environmental benefit.
