EFFECTIVE UTILISATION OF COPPER SLAG IN CONCRETE

concrete

Properties of concrete with copper slag as fine aggregate replaced were studied. Control concrete with normal fine aggregate and copper slag concrete with 0-30% fine aggregate replacement with copper slag were made. Constant water to cement ratio of 0.4% was maintained for all the concrete. Properties like compressive strength investigate in the laboratory. The result showed that density of the concrete decreases with increases in copper slag percent. Compressive strength of copper slag concrete were lower than control concrete. This paper reports the effect of concrete using copper slag as fine aggregate replacement. In this project work concrete grade M40 was selected and IS method was used for mixed design. The properties of material for cement, Fine aggregate, coarse aggregate and copper slag were studied for mix design. The maximum compressive strength of concrete attained at 30% replacement of fine aggregate at 7, 14 and 28 days. The compressive strength of concrete attained at full replacement of fine aggregate at 7, 14 and 28 days. The rebound hammer test showed higher compressive strength at 30% fine aggregate replacement, this is due to uniformity of concrete. The pulse wave velocity is higher for the 30% fine aggregate replacement, its understood that the density of mix is high and free from pores.
