Abstract
Since globalization, day by day construction activities have enormously taken place. The raw materials used for making concrete have become an acute shortage, especially
aggregates. In the present study, we have made an attempt to replace natural crushed
coarse aggregate by cinders, which is a by-product of steel manufacturing industry in slag
based concrete blocks. Blocks of size 400*200*150mm are chosen and mix proportion is
selected as per IS: 2185 i.e., 1:4:8 and w/c is 0.6. The blocks were casted by replacing (0%,20%,40%,60%,80%, & 100%) natural crushed coarse aggregate by cinders using concrete block making machine (egg laying machine), and cured for 28 days. After curing, the blocks were tested to know the mechanical properties such as compressive
strength, modulus of elasticity and water absorption. From the results obtained, 20%
replacement is found to be suitable in terms of strength development, water absorption and modulus of elasticity.
