Abstract: Bentonite can also be used as low-cost construction material which can reduce energy consumption by blending with OPC up to certain percentage and can store natural resources and also can give solution for environmental problems which have cement production as well as which affects the durability and life cycle of the concrete structures. Fly ash contains very minute particles which can make the concrete highly dense, reduce the permeability of concrete, and also adds greater strength to structures and generates low heat of hydration. By partial replacement of OPC with bentonite and fly ash can reduce greenhouse effect and improves the durability of the concrete. In this paper, OPC is partial replaced with bentonite and fly ash with same proportions of 5%,10%’15%,20% and its compressive strength of concrete is studied by testing 81 cubes and the results were compared with that of controlled concrete. Durability of concrete with partial replacement of bentonite and fly ash with OPC were also studied by testing 108 specimens through RCPT equipment (rapid chloride penetration test) and the results were compared with that of OPC concrete.
