- Abstract
Self-Compacting Concrete (SCC) is gaining popularity due to several advantageous characteristics. SCC can settle into the formwork without any mechanical vibrations. This investigation aims to develop brick aggregate-based SCC as well as use waste material as a partial replacement of cement to reduce costs and simultaneously improve both fresh and mechanical properties. For this purpose, locally available 12.5 mm downgraded brick chips were used as a coarse aggregate, and waste material ladle refining furnace slag (LRFS) powder was used as a partial replacement for cement. LRFS powder was mixed with concrete at proportions of 5%, 10%, and 15%. It was observed that an increase in LRFS powder content in the concrete increases the slump flow value, reduces the V-funnel flow time, and increases the L-box blocking ratio. After satisfying the fresh properties of SCC, 108 cylindrical molds were cast and cured at room temperature for 14, 28, and 56 days. After proper curing, compressive strength, splitting tensile strength, and modulus of elasticity tests were performed, showing that LRFS powder improves the compressive strength and tensile strength of the concrete. This investigation revealed that SCC with 5% and 10% LRFS powder, initially showed better performance, but after 56 days, a downward trend in compressive strength was observed. In contrast, SCC with 15% LRFS powder, demonstrated superior performance both in the early and later ages. Therefore, this research suggests that using 15% LRFS powder as a replacement for cement in brick aggregate base SCC will yield better performance.
