摘要：

This study investigates the fresh properties of self-compacting concrete incorporating electric arc furnace oxidizing slag as coarse aggregate. A binary blend of 30% fly ash and cement was utilized as binder to improve the performance of concrete in its fresh state. Concrete grades M20, M30 and M40 were developed by replacing natural coarse aggregate with 50% and 100% electric arc furnace oxidizing slag (EAFOS) aggregate. Thus, fresh properties of SCC; slump flow, T500, U box, V funnel and L-box were determined. From the evaluation of fresh properties, it is shown that the grades of concretes developed passed the set standard limits for SCC. The results showed that 50% EAFOS addition to SCC will not deter its fresh properties in any way, however, when EAFOS was added up to 100%, there was reduction in workability properties of the concrete. The study showcases the significant potential of EAFOS as an alternative aggregate in SCC. Thus, the data provided in this study will be useful for concrete constructors.
