Self-Compacting Concrete (SCC) used for pavement, structure, hydraulic structures, and barrier construction purposes must possess sufficient mechanical and impact-resistant properties. The study examined the performance of SCC concrete made using Dimensional Limestone Slurry Waste (DLSW) obtained from discarded waste from the stone manufacturing unit. An experiment that was carried out using DLSW as fine aggregate (Natural Sand) in self-compacting concrete (SCC) at varying replacement percentages, i.e., 15, 30, 45, 60, 80, and 100% by weight of fine aggregate. The compressive strength, flexural strength, and impact resistance properties were measured on the hardened state of DLSW-modified SCC. In addition, empirical correlations were established between the mechanical properties and impact energy at the fracture on the modified SCC series. The microstructure study was also examined, and the findings were supported. The results proved that DLSW-modified SCC had superior mechanical and impact resistance to control concrete up to 30% DLSW substitution to the fine aggregate. This inclusion of waste in the production of SCC would help to obtain the “Sustainable Development Goals” (SDGs).

摘要

Self-Compacting Concrete (SCC) used for pavement, structure, hydraulic structures, and barrier construction purposes must possess sufficient mechanical and impact-resistant properties. The study examined the performance of SCC concrete made using Dimensional Limestone Slurry Waste (DLSW) obtained from discarded waste from the stone manufacturing unit. An experiment that was carried out using DLSW as fine aggregate (Natural Sand) in self-compacting concrete (SCC) at varying replacement percentages, i.e., 15, 30, 45, 60, 80, and 100% by weight of fine aggregate. The compressive strength, flexural strength, and impact resistance properties were measured on the hardened state of DLSW-modified SCC. In addition, empirical correlations were established between the mechanical properties and impact energy at the fracture on the modified SCC series. The microstructure study was also examined, and the findings were supported. The results proved that DLSW-modified SCC had superior mechanical and impact resistance to control concrete up to 30% DLSW substitution to the fine aggregate. This inclusion of waste in the production of SCC would help to obtain the “Sustainable Development Goals” (SDGs).
