Increasing urbanization and industrialization is raising burden on existing natural resources used in construction industry which is leading to severe environmental issues. Using industrial waste materials in construction can be one alternative to curb this problem. Geopolymer concrete (GPC), known as the next generation of concrete, is more durable and environment friendly as compared to conventional concrete. The current investigation presents the effect of waste foundry sand (WFS), a by-product of foundry industries.0This0review discusses0the synthesis0of alkali-activated0binders0from0blast furnace0slag, quarry dust and0fly ash, the natural sand was replaced by WFS in the range of 0% to 100%. Tests on hardened concretes, to study, compressive strength, split tensile strength and flexural strength, were conducted to assess the strength. Addition of WFS lowered the workability of GPC. Tests were carried out on 0%, 50% and 100% WFS replacement for finding the optimal percentage again tests were carried out on 10,20,30&40 percent, 20% WFS gained highest strength and compressive split tensile and flexural strengths and that can be used for application purpose.
