Abstract
The construction industry relies heavily on cement for its operations in the development of shelter and other infrastructural facilities. Various research workers in the recent past had look into the utilization of agricultural wastes that are known to be puzollanas to partially substitute cement that is the major component of concrete. The use of Ordinary Portland Cement (OPC) and Rice Husk Ash (RHA) concrete in minimizing thermally induced expansion cracks has been identified. The utilization of Groundnut shell will promote waste management at little cost, reduce pollution by these waste and increase the economic base of the farmer when such waste are sold thereby encourages more production. Also, GSA production required less energy demand compared with cement production and safe the needed foreign exchange spent on importation of cement or its constituents.The effective utilization of these sea shell wastes which are available almost free of cost and in abundance will not only reduce their pollution tendency but will help in reducing the amount of cement used in concrete work. Investigations are made in order to perform the partial replacement for cement in concrete by Groundnut Shell Ash and Sea shell powder.
