Stone Dust in Concrete: Effect on Compressive Strength

Stone dust may be a waste obtained from crusher plants. it's potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve the standard of concrete but also conserve the natural river sand for future generations. In the present investigation, an experimental program was administered to review the workability and compressive strength of concrete made using stone dust as partial replacement of fine aggregate within the range of 10% - 100%. M25 grade of concrete was designed using Portland pozzolana cement (PPC) for referral concrete. Workability and Compressive strength were determined at different replacement level of fine aggregate viz a viz referral concrete and optimum replacement level was determined based on compressive strength. Results showed that by replacing 60% of fine aggregate with stone dust concrete of maximum compressive strength are often made as compared to all or any other replacement levels.
