Abstract
The stone processing generated Dimensional Limestone Slurry Waste (DLSW) was used in Self-Compacting Concrete (SCC) to evaluate the compressive strength and analyze microstructure. X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) analysis of DLSW was carried out, and its results revealed the presence of CaO (38.93 %) and SiO2 (24.33 %), which was associated with calcite and quartz. The rough, angular shape of particles, fineness, and presence of calcite of DLSW help to get optimum density and enhanced compressive strength at 28 days in modified SCC up to a 45 % replacement level. The Mercury Intrusion Porosimetry (MIP), Scanning Electron Microscopy (SEM), Energy Dispersive Spectrometer (EDS) and Ultrasonic Pulse Velocity (UPV) analysis results support the improvement of compressive strength claims.
