Abstract

This study aims to investigate the influence of pozzolanic materials and waste products on the strength properties of self-compacting concrete (SCC). Specifically, the research uses calcined kaolin clay (CKC) and waste marble powder (WMP), as supplementary materials. The study examines various blending systems, including binary, and ternary mixtures. Test samples were prepared by manipulating the weights of cement components, incorporating CKC, and WMP at different proportions. Fresh properties, such as L-Box, segregation resistance, V-funnel resistance, and slump flow diameter, were evaluated. Hardened properties were assessed at three intervals: 7, 28, and 56 days. The optimal binary mixture demonstrated potential as a substitute for CKC, and WMP improving fresh results and enhancing compressive strength. Ternary blends exhibited higher compressive and tensile strengths. The results indicated that binary blended mixes with 10% WMP showed enhanced compressive strengths compared to other combinations. Furthermore, the binary blend with 10% WMP displayed superior compressive strengths at all ages compared to other combinations. Additionally, the ternary blends showcased higher compressive and tensile strengths values, reaching 61.8 MPa, and 4.49 MPa, respectively. The durability performance of the binary and ternary blends SCC is examined in terms of water absorption. In addition, the study successfully met its objectives by lowering the requirement for cement, lowering CO2 emissions, and improving the environmental impact of (SCC). These findings provide valuable insights for the construction industry, promoting the utilization of alternative materials in producing high-performance self-compacting concrete.
