Cement plays a major role in the production of paver blocks. Cement manufacturing industries pollutes the surrounding areas. The main objective of this work is to reduce the use of cement in the concrete paver block by partial replacement with rice husk ash. An experimental investigation is conducted to analyze the compressive strength, water absorption and flexural strength of paver blocks with partial replacement of cement by rice husk ash dumped near Chengapalli, Tiruppur. Rice husk ash were collected from the dump yard and utilized for experimental investigation after doing the initial cleaning process and property study of material. Cement replacement with Rice husk ash were done in proportions of 10% 20%, 30%, 40% and 50% in volume of concrete. Various strength parameters like compressive strength, flexural strength and water absorption were determined. Weight of concrete blocks is considerably reduced with increase in the amount of rice husk ash.
