Experimental Study on Performance of Concrete Using Partial Replacement of Cement by Metakaolin

Test results were obtained for normal concrete, concrete with partial replacement of cement by Metakaolin, concrete with partial replacement of cement by Metakaolin and Steel Slag, accelerated curing results of concrete with partial replacement of cement by Metakaolin. For Compressive Strength cubes of size 100 mm x 100 mm x 100 mm were cast and tested at 7, 21, and 28 days of curing period. The addition of 15% of Metakaolin as replacement to cement shows optimum enhancement in properties of concrete, with increase in Strength parameters as high as 48% in comparison to control mix. Hence Metakaolin up to 15% replacement can be utilized as a partial replacement to cement in binary blend as well as ternary blend with Steel Slag for high Strength, accelerated Strength and high durability concrete.
