Fine aggregates, such as sand, are essential in concrete production as they fill the voids between coarse aggregates, minimize friction, and enhance both the workability and durability of the concrete. Currently, significant research is focused on identifying sustainable alternatives to natural river sand. One promising approach is the use of industrial waste materials, including waste foundry sand, steel slag, copper slag, blast furnace slag, and coal bottom ash, as substitutes in concrete production. This not only addresses the depletion of natural resources but also offers a solution to waste disposal challenges, providing an eco-friendly alternative to traditional practices. The present study deals with an effective utilization of crushed sand, bottom ash, and grit as substitute of natural river sand in concrete on the basis of grading, water absorption, specific gravity, voids content and bulk density. Results are validated for M25 concrete using natural river sand as fine aggregate which is replaced by crushed sand, bottom ash, and grit on the basis of workability and compressive strength. It is observed that the natural river sand can be replaced fully by crushed sand and or with different combination of bottom ash and grit which confirming to grading zone II without any problem.
