Comparative Strength Analysis of Sustainable Concrete Incorporating PPSA, RCA, and M-Sand

Abstract The growing demand for sustainable construction materials has encouraged the utilization of agricultural waste and recycled construction materials in concrete production. This review examines the strength performance of sustainable concrete incorporating Pigeon Pea Stalk Ash (PPSA) as a partial cement replacement, Recycled Coarse Aggregate (RCA) as a replacement for natural coarse aggregate, and 100% Manufactured Sand (M-Sand) as fine aggregate. Published studies indicate that the incorporation of PPSA and RCA can produce concrete with satisfactory mechanical properties when used within optimum replacement limits. The reviewed literature shows that replacement levels of up to 2% PPSA and 30% RCA, combined with 100% M-Sand, can achieve the strength requirements of M30 grade concrete. Among the reported mix combinations, a maximum compressive strength of 43.95 MPa at 28 days was observed for the optimum mix. The findings demonstrate that PPSA, RCA, and M-Sand can effectively reduce the consumption of natural resources while maintaining adequate strength performance, making them promising materials for sustainable concrete applications.
