The waste product (rice husk ash) is already causing very serious problem of surrounding environmental pollution which causes for most way to handling for this ash. The rice husk ash was mainly contains silica and aluminium ion contents. In this experimental research conducted on Rice Husk Ash (RHA) concrete to analyse the compressive strength and to study its water absorption properties. The preparation of rice husk ash concrete, cement was replaced by weight at different percentage levels like as 0%, 5%, 10%, 15%, 20% and 25% with M20 grade of concrete and 0.50 water cement ratio. The various fresh and harden concrete properties test was conducted like compaction factor and slump cone test as well as harden concrete properties like compressive strength and water absorption properties at the age of 7 and 28 days obtained. The experimental results shows that the maximum replacement level of 20% with weight of cement. Beyond limits of increasing level of cement strength will be reduced.
