Abstract
Rice has been the major crop in India and the production of rice has been increasing through years. Many Rice mills have been established across the country for the rice grains to be processed and during this process Rice Husk has been left out as a waste product. It was being used in boilers as fuel and as a result after its burning ash was being left out which was creating serious environmental hazards. For this issue many ideas has been implemented and one of them was using it as a replacement material in the cement as fine particles this is because of the pozzolanic activity of the Rice Husk Ash when mixed with cement resulting in the increase of the strength. And this project gives the detail study of the strength variation of the conventional cement mortar mix to the Rice Husk Ash added mortar in 5%, 10%, 15%, 20% and 25% by weight to the four Grades of cements namely OPC-53, OPC-43, PPC, PSC which were cured for 3, 7, 14, 28 and 56 days respectively. And the conclusions of the experiment showed that the optimum percentage of the Rice Husk Ash for achieving maximum strength that can be 10% for OPC-53 and OPC-43 Grade cement and 5% for PPC and PSC Grade cements after 56 days strength test respectively.
