ENHANCE THE PROPERTIES OF CONCRETE USING WASTE MATERIALS

In this study waste sawdust ash and rice husk ash were used. Sawdust ash was use as partial replacement of cement at 10%, 20%, and 30% by weight in concrete mix. Rice husk ash was use as partial replacement of cement at 10% and 20% by weight in concrete mix. A total 15 number of concrete mix was prepared, in each mix 12 cubes of size 150 x 150 x 150 mm and 4 cylinder of size 100 x 200 mm were prepared. Compressive and splitting tensile strength of concrete mix was increasing at 10% replacement of saw dust ash with respect to control mix. At 20 and 30% replacement strength was decreasing. Compressive and tensile strength of concrete mix was decreasing as increasing rice husk ash percentages.
