Abstract - The main aim of the study is to search an alternative for cement to reduce carbon footprints. The world's yearly creation of concrete of 1.6 billion tons discharges 7% of the worldwide stacking of carbon dioxide into the air and it is likewise the most vitality escalated material of development which is in charge of the emanation of extensive measure of greenhouse gasses into the environment. Bentonite is exceedingly plastic mud containing around 85% earth minerals and montmorillonite. In this project work am attempt has been made to study the mechanical behaviour of concrete with the partial replacement of cement with bentonite. compressive strength split tensile strength and flexural strength were perform and result's have been tabulated, it was seen from the results that bentonite resulted in poor early stage and good later stage,the results of  compressive strength, split tensile strength and flexural strength were compared with the conventional concrete. Fibrofor fibers are introduced in order to arrest the micro cracks and increase the tensile strength of the concrete. Mix design has been done as per Indian code. In Present work bentonite was varied for 25%, 30% and 35% and fibrofor fiber 1kg/m²is kept constant.

Key Words: Bentonite, Fibrofor fiber, compressive strength, split tensile strength and flexural strength
