EXPERIMENTAL INVESTIGATION OF STRENGTH PARAMETERS OF CEMENT AND CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH INDIAN CALCIUM BENTONITE

Portland cement is one of the expensive materials of concrete, causes a ton of harm to nature by the outflow of CO2 gas into environment amid hydration procedure to accomplish quality, the primary target of this paper is to create ease and eco amicable restricting material by incomplete substitution of cement. Indian calcium bentonite is expansive clay, is tend to increase the volume by addition of water and obeys pozzolanic properties. The experimental investigation in this paper deals with the determination of strength properties of Portland cement and concrete by partial replacement (10, 15, 20, 25 and 30) of Portland cement with a mass of Indian calcium bentonite. The higher consistency values observed in a blended binder than OPC. The Indian calcium bentonite mortar mixes shown higher compressive strengths at 10% replacement, equates at 15% then decreasing towards 30% than controlled mixes. Lower strengths were observed in Indian calcium bentonite concrete mixes, at the ages 3days, 7 days as well as 28 days of curing.
