Rigid Pavement Concrete by Adding GGBS and River Sand in Accelerate Curing Method

Abstract

This method of concrete mix design consists of selection of optimum properties of ingredients, i.e., cement, mineral admixture, fine aggregate, coarse aggregate, water and chemical admixture if needed to produce concrete specified properties such as strength, workability and durability, etc. as economic as possible. The compressive strength of hardened concrete which is generally considered to be an index its properties depends upon its factor, e.g., quality, quality of cement, water, aggregate; placing, compacting and curing. The cost of concrete is made up of cost of material the variation in cost of material a rise in fact that in cement several time costly then aggregate thus the aim to produce a lean mix. In this paper, concrete pavement has designed by adding mineral admixture in reduction of cement content up to 32% and reduce the cost of concrete mix and also to attain its equal strength of concrete.
