Concrete is major civil engineering construction material, because the ingredients of concrete are locally available materials. In ordinary concrete the cement is used as major binding material. The usage of cement in concrete causes lot of environmental pollution due to emission of greenhouse gases. So that it is necessary to reduce usage of cement by introducing new supplementary cementitious materials which are the by-products of industries to reduce debris. The rice husk ash is one of the by product which is released from paddy. The usage of rice husk ash in concrete leads to development of high strength concrete and also reduces the self-weight of the structure. In this study, partial replacement (by weight) of cement with RHA and silica fume with glass powder in paver blocks is used for determining the change in the compressive strength, water absorption of paver blocks. Partial replacement of cement in different percentage as like 10%, 20%, 30% and 40 % has been done. The compressive strength has been determined at the end of 7, 14 and 28 days, water absorption test has been determined at 28 days.
