Abstract: The effect of waste foundry sand (WFS) as a partial substitute for fine aggregates (natural sand) on concrete mixtures was investigated using an experimental program. The 28-day compressive strength of control concrete mixtures (M25) was engineered to be 31.60 MPa, respectively. The fine aggregate (natural sand) was then replaced with a replacement ratio (0%, 5%, 10%, 15%, 20%) of WFS by weight. The focus of this study is to prevent sandpits from being dug up, as a result of the construction industry’s rapid production of a variety of fine aggregates. Compressive strength, splitting tensile strength, flexural strength, carbonation depth, water absorption, were used to investigate the performance of concrete for up to 56 days. In this analysis, 105 concrete specimens were cast. The specimens were prepared for concrete mixes of M25 grade, with a water-to-cement ratio of 0.50. This research looked at the impact of waste foundry sand on various properties of concrete. The properties of fresh and hardened concrete were determined by testing specimens of concrete mixes.Mechnaical properties and durablity Properties of M25 grade concrete increased with the up to 15% replacement ratio, however there is a small declination found at above 15% replacement ratio.
