Impact of Admixture and Rice Husk Ash in Concrete Mix Design

Abstract

In this paper an attempt has been made to show the impact of Admixtures and Rice husk on concrete structures by conducting an experimental study in the laboratory to improve the cubic strength of concrete structures. Super plasticizer Conplast 430: G-8 as an Admixture is added in concrete mix design. Compressive strength of concrete cubes with Admixture at 7 and 28 days for M-20 grade has been found to be Superior as compare to without Admixture. Similarly, Rice husk ash as a partial replacement of cement is added in the concrete mix design and a detailed parametric study for 5% and 15% Rice husk has been carried out on compressive strength of concrete cubes for M-20 mix at 7 and 28 days. The results shows that compressive strength of concrete cubes has been improved by adding Admixture and Rice husk (as a partial replacement of cement) in the concrete mix design.
