Experimental study on compressive strength of concrete by partially replacement of cement with sugar cane bagasse ash

Use of waste material in concrete is important for environmental aspect. Sugar cane bagasse ash is a waste by\ud product of sugar mill. Present study is to investigate impact of sugar cane bagasse ash in concrete. In this\ud experimental work sugar cane bagasse ash which is taken from Maroli sugar mill, Navsari, Gujarat, INDIA is\ud partially replace with cement at 0%, 5%, 10%, 15% and 20% by weight in concrete. The grade of concrete is\ud M25 and w/c ratio is 0.49 taken as a reference. 150*150*150 mm cubes are casted and tested for 7, 14, 28 and\ud 56 days. Compressive strength result shows that up to 10% replacement of sugar cane bagasse ash in concrete\ud gives comparable result with normal concrete without any admixture, but 5% replacement give maximum\ud compressive strength. Also the amount of sugar cane bagasse ash increase, workability of concrete increases
