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. Mechanical properties and durability 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.

1.Introduction
New techniques and technologies are being implemented on a daily basis to meet the demands of rapid industrial development. Significant quantities of solid and toxic waste in the form of products resulted from the use of these methods to manufacture materials and goods. Waste can be used to create new items, allowing for more productive use of natural resources. Sustainability has three components: the environment, the economic system, and culture. Its aim is to ensure that life on Earth can be sustained in the future. Sustainable development must preserve the health
