This article discusses the performance of polishing powder as a cement replacement in cement mortar. This cement is replaced with polishing powder in six different proportions of 5, 10, 15, 20, 25, and 30% by weight for research purposes. Cube compressive strengths are calculated for 3, 7, 14, 28, and 90 days. The split, flexural strengths are evaluated for 28 and 90 days. The study found that replacing 15% of the cement with stone polishing powder improves strength and XRD and SEM analysis were used to back up the findings.
