Influence of waste glass aggregates on the rheological properties of self-consolidated concrete

Abstract

Implementation of self-consolidating concrete (SCC) leads to the evaluation of more attractive, quality-controlled concrete with improved workability in the construction sector. The aim of the paper involves the determination of the rheological properties of SCC using waste glass aggregate, which affects the concrete’s rheological behaviour. In this research, the conventional coarse aggregate was substituted by the waste glass aggregate (WGA), at 10%, 20% and 30%, respectively. The consequence of adding waste glass in fresh concrete was inspected by several tests such as density, slump flow, J-ring, L-box and V-funnel test. These properties were then compared to the corresponding properties of normal-weight concrete. Test results specify that the WGA amplified the slump value of SCC thus indicates the improved workability. The decreasing density of the SCC leads it to the lightweight concrete. Subsequently, the SCC concrete shows relatively reduction in the passing ability with the addition of waste glass due to the angular shape of the glass bits. Hence, the study concludes that all of the rheological properties of self-compacting glass concrete (SCGC) made of WGA showed an impressing enhancement in the result, in comparison with the conventional SCC.
