Abstract-The possibility of granite waste and waste foundry sand (WFS) as sustainable substitutes for fine and coarse aggregates in M40-grade concrete is examined in this study. A by-product of the ferrous and non-ferrous metal casting industries, WFS was added at replacement levels of 5%, 10%, 15%, and 20% by weight of fine aggregate. The highest limit was chosen at 20% since strength decreases beyond this percentage. At the same substitution levels, granite waste a byproduct of the stone processing industry—was also used as a partial substitute for coarse aggregates. To investigate their combined impacts on concrete, two experimental scenarios were examined: one with a constant 20% WFS replacement and different percentages of granite waste, and another with simultaneous fluctuations in both WFS and granite waste content.
