Foundry sand is generally of two types: Green sand, Chemically bounded sand. Additive in sand depends on type of metal casting. Use of waste foundry sand as full or partial replacement by fine aggregate helps to achieve different properties or behaviour of concrete.

In the United States alone, the foundry industry discards up to 10 million tons of sand each year, offering up a plentiful potential resource to replace sand in concrete products. However, because the use of spent foundry sand (SFS) is currently very limited in the concrete industry, this study investigates whether SFS can successfully be used as a sand replacement …
the use of foundry sand waste (FSW) on concrete properties. The properties on the fresh state were evaluated by means of flow table test and the determination of the incorporated air content. On the hardened state, compressive strength tests were performed. Their initial results have shown that the use
The silica sand in the mix was replaced by 50% FSW to produce concrete paver in the ratio of 1:1:2, 1:2:4 and 1:3:6. These ratios represent cement: silica sand + FSW: coarse aggregate. The ratio that produced the maximum compressive strength per concrete paver sample is the ratio 1:1:2 and this is similar to the split tensile strength test.

The reason of the increment in compressive strength in addition to recycled foundry sand may be due to creating denser concrete matrix and higher silica substance existing within the RFS. Normally silica content available in river sand is in the range of 75–80% whereas for foundry sand it is 80–90% [4], [6], [9].

The by-product of the foundry industry is waste foundry sand (WFS). The use of WFS in building materials will safeguard the ecosystem and environmental assets while also durable construction.
Foundry sand is the raw material required for making metal-casting sand molds, which are frequently recycled during the casting process. Foundry sand loses its quality after repetitive use, making it unsuitable for use in the process of manufacturing products, and later, is subsequently thrown away as waste, i.e., WFS (Ankush et al., 2017).High-quality silica sand …
