Over-extraction of aggregates from natural sources with rapid urbanization as well as massive waste generation in construction industry have imposed the need to utilize waste material as concrete constituent. Crushed Stone Dust (CSD) is such a supplementary material that can be utilized for the production of sustainable concrete. This study attempts to predict and optimize fresh and hardened properties of concrete utilizing CSD as a partial replacement of natural fine aggregate and Nylon Fiber (NF) as fiber reinforcement using Response Surface Methodology (RSM).

- The increasing demand for concrete is depleting natural sand resources, leading to environmental issues, particularly from river sand extraction.
- Utilizing waste materials like stone dust as a fine aggregate in concrete can reduce natural resource usage and address landfill problems while improving concrete properties when combined with nylon fiber reinforcement.
- This study investigates the combined effects of varying stone dust (20%-50%) and nylon fiber (0.25%-0.75%) proportions, along with different water-cement ratios, on the compressive and tensile strength of concrete, finding optimal percentages for strength enhancement while noting strength decreases with higher water-cement ratios and excessive stone dust.
