EXPERIMENTAL INVESTIGATIONS ON PARTIAL REPLACEMENT OF STEEL SLAG AS COARSE AGGREGATES AND ECO SAND AS FINE AGGREGATE

Concrete is the 2nd highest using material in this world. Continuous utilization of coarse and fine aggregates for concrete we are facing different problems like lack of availability of these aggregates with good quality. To overcome this problem replaced the aggregates with eco-sand and steel sag. The primary objective of the project is to increase the strength of the concrete by replacing coarse aggregate by steel slag and also 30% replacement of eco sand as fine aggregate. As of from literature steel slag is replaced for 0,15,30,45,60,75,90 % which indeed gives us 7 mixes (M1, M2, M3, M4, M5, M6, M7) totally. After conducting various tests we can arrive to conclusions of mixes M1, M2, M3, M4 are relatively good strength than conventional mix. Particularly the mixes M3, M4 which consists of 30 & 45 % of slag has high strength in all tests. It is evident that 50 % or more is not feasible as the strength found is very low compared to conventional mix
