Abstract
Production of residues from industries and construction sector has increased during last few years. Much of these wastes have been thrown to land fill, without considering its potential for reuse and re-cycling as well. The aim of this practical work, is to study the properties and the respective strength that is (compressive strength) gained by M-20 Grade of concrete mix, prepared under controlled condition. The laborites test have follow the IS Standards. The results vary according to the proportions of supplementary constituent added to the mix. The substitution of cement concrete with basic oxygen furnace slag (BOFS) and then followed by iron cutting waste (ICW), produces a significant increase in compressive strength in both the cases i.e., by adding basic oxygen furnace slag & iron cutting waste. The above said waste material not only makes the concrete mix prepared, suitable for use, but also improves the strength of mix and makes the mix economical as well. In the M-20 concrete mix, sand is replaced with BOF Slag and then with ICW in the varying range of 10%, 20% and 30% by weight. The test is carried out to evaluate the compressive strength of controlled M-20 Grade of mix after 7 and 28 days of casting.
