Abstract:
This study investigates the feasibility of using induction furnace slag as a substitute for river sand/manufactured sand (M-sand) in the production of concrete. The properties of concrete made with slag fine aggregate is compared with concrete made of river sand and M-sand. Experimental studies have been carried out on concretes made of three types of aggregates and two types of cement (ordinary portland cement [OPC] and portland pozzolana cement [PPC]). Mechanical and durability property tests performed according to standards showed that the characteristics obtained for the concrete made with slag aggregate is comparable with that of the concrete made with river sand and M-sand. This study suggests the 100% replacement of conventional fine aggregate with slag fine aggregate for the production of concrete without compromising the strength and durability characteristics. Further, the study demonstrates that with the suitable measures, the high water absorption of slag aggregate can be compensated.
