This experimental study investigates the influence of granite powder and bottom ash as partial replacements in manufactured sand (M-sand) on the properties of concrete. Fine aggregates play a crucial role in determining the strength and durability of concrete. However, natural sand resources are depleting, prompting the need for sustainable alternatives. Manufactured sand, a byproduct of crushed stone, offers a viable substitute. In this study, granite powder and bottom ash were used to partially replace M-sand in varying proportions (10%, 20%, 30%, 40%, and 50%) to analyze their effects on fresh and hardened properties of concrete. Standard M30 grade concrete was used to maintain consistency across all mixes. Tests such as workability, compressive strength, split tensile strength, and flexural strength were conducted at 7 and 28 days of curing. The results indicate that moderate replacement levels improved certain strength parameters, while higher replacements led to marginal reductions in strength. This study promotes the utilization of industrial and construction waste in concrete, enhancing sustainability and minimizing environmental impact.
