Experimental Study on Compressive Strength of Concrete by Using Metakaolin

The present study investigates the effects of Metakaolin & Super plasticizer on strength properties of M-35 grade concrete. The experimental program is designed to find the compressive strength of concrete by partially replacing the cement in concrete production. The replacement levels of cement by metakaolin are selected as 4%, 8%, 12%, 16% and 20% for constant water- cementitious material ratio of 0.43. For all mixes compressive strength is determined at 3, 7, 28 days for 150 X 150 X 150 mm size cubes. Current experimental study shows that 12% replacement of cement by metakaolin gives higher strength.
