Construction sector is a fast growing industry and concrete is a prominent construction material in the present scenario .The rapid development of urban infrastructures requires huge quantity of raw materials needed for the concrete manufacturing. The cement manufacturing industry is a major contributor of carbon dioxide (CO2) that results in 5% of global man-made emissions, out of which 50% comes from the chemical process and 40% from fuel combustion. [1] The primary sector of the economy means the sector which makes direct use of natural resources. In most of the developing and under developed countries, primary sector is the biggest part of the economy. Dependence on this sector has also resulted in the production of substantial quantities of waste materials. These wastes are normally dumped into landfill thereby causing environmental issues. Under these circumstances it is of prime most importance to derive supplementary cementitious materials (SCMs) from agricultural wastes that can be used as a cement replacing material. The foremost aim of this paper is to review the possible use of different agricultural wastes as SCMs that can reduce use of cement usage, and their engineering impacts on the different properties of concrete. © IAEME Publication.
