STENGTH ANALYSIS CONCRETE COMBINATION WITH RICE HUSK ASH OF DIFFRENT GRADE OF CONCRETE

Abstract

In this paper an attempt has been made to show the impact of Rice husk ash as a partial replacement of cement on concrete structures by performing an experimental study in the laboratory to improve the compressive strength of concrete structures. Compressive strength of concrete cubes by mixing rice husk ash tested at 7, 14 and 28 days for M-20, M-25 and M-30 grade has been found to be Superior as compare to without Admixture. Rice husk ash as a partial replacement of cement is added in the concrete mix design and a detailed parametric study for 10%, 20% and 30%. The results shows that compressive strength of concrete cubes has been improved by adding Rice husk (as a partial replacement of cement) in the concrete Mix design.
