Effect Of Quartz Particle Size and Cement Replacement on Portland Limestone Cement properties DOI:  https://doi.org/10.30564/jbms.v4i2.5091 Abstract This research focuses on investigating the effect of quartz particle sizeand cement replacement on their physicomechnical properties. Portlandlimestone cement (PLC) was employed and replaced with quartz powder(QP) at various particle sizes (1.19 mm, 425 µm, 300 µm, 212 µm, <212µm) and cement replacement between 2.5 wt.% ~ 15 wt.% at interval of2.5 wt.% to study their impact on the cement properties. The PLC chemical composition revealed a relatively low lime and high silica contentcompared to the conventional cement. QP revealed a high silica, lime andsulphur contents compared to natural sand. A high consistence, elongatedsetting times and lower strengths and specific gravities were observed ascement was replaced with QP at a given particle size respectively. Theeffect of replacing cement with QP content between 2.5 wt.% and 15 wt.%...
