520			_aThe increasing demand for sustainable construction materials has encouraged the use of waste materials. This study investigated the effects of Pulverized Perna viridis and Rice Husk Ash as sustainable supplementary cementitious materials on the compressive strength of cement mortar. An experimental research design was employed, using three mix proportions: 0% replacement as the control mix, 5% replacement, and 10% replacement of cement with the combined supplementary cementitious materials. Mortar specimens were cast into 50 mm × 50 mm × 50 mm cube molds and cured for 7, 14, and 28 days before compressive strength testing. The results were analyzed using mean compressive strength and standard deviation. Findings showed that the compressive strength of mortar mixtures increased as the curing period progressed. However, higher replacement levels of Pulverized Perna viridis and Rice Husk Ash produced lower compressive strengths than the control mix. The control mix achieved the highest compressive strength, while the 5% replacement performed better than the 10% replacement. The study concluded that these waste-derived materials influenced the strength performance of cement mortar and demonstrated their potential as supplementary cementitious materials. The findings contribute to sustainable construction by promoting reuse of agricultural and marine waste while reducing dependence on conventional cement materials.
