Waste foundry sand (WFS) is a by-product of the foundry sector. While ensuring enduring construction, the usage of WFS in building materials will protect the environment and its resources. The use of industrial waste in concrete compensates for a lack of environmental resources, resolves the problem of trash dumping, and offers another form of environmental protection. In the last several decades, a number of researchers have looked at whether WFS may be used to produce concrete instead of natural river sand in an effort to solve the problem of WFS in the foundry region and achieve its recycling. However, it is noted that there is a dearth of understanding regarding the development of WFS in the manufacturing of concrete, necessitating a compressive study. The current study investigates a number of characteristics, including the physical and chemical makeup of WFS, its new features, and the mechanical and durability performance of concrete using WFS as a partial replacement. The results of several research indicate that replacing WFS up to 30% boosted the concrete's durability and mechanical strength to some amount, but that as the replacement level of WFS grew, the workability of fresh concrete decreased. Future study should combine WFS with pozzolanic material or fibre reinforcement, according to this review.
