Abstract: Rice husk ash (RHA) is one of the promising pozzolanic materials that can be blended with Portland cement for the production of durable concrete and the reduction of the environmental impact of the cement industry. Rice husk ash was used in this study for partial replacement of cement in concrete production, which was classified through its oxides composition and thus indicates a high content of SiO2 proving it to be a good pozzolana material. The rice husk is burnt into ash to produce rice husk ash (RHA), the mechanical properties of RHA was determined and cement was partially replaced at the ratio of 5%, 10%, 15% and 20 % respectively. Concrete grade M20 was used and compressive strength of 7 days, 14 days and 28 days are determined according to BS 8110. The study found that the optimum replacement of rice husk ash (RHA) in cement was 15% which is having very significant variation with the strength of concrete without rice husk ash (RHA) and thus conforms to findings of other researchers.
Keywords: Rice husk ash (RHA), cement, medium grade concrete, compressive strength.
