Abstract
AbstractIndustrial waste has rapidly increased day by day due to the fast‐growing population and usage of products, which dumps unscrupulously, resulting in environmental pollutions. Waste foundry sand (WFS) is one of the industrial solid wastes. River sand is generally used in concrete as a fine aggregate, which is limited (scant), and river excavation for sand leads to environmental deterioration. To resolve these problems, a study was performed on WFS as a partial substitution instead of natural sand in concrete. The effects of WFS on concrete performance were assessed through durability and mechanical performance. The results from experimental tests show that, compared to concrete blends with WFS up to 30% substitution, the control mix strength was only 7.6% (28 days) higher, and this improvement is not too high. In the same manner, concrete mixtures that contain WFS up to 30%, and their durability properties were somewhat same to blank max (control). Test results showed that WFS with a substitutions ratio up to 30% can be successfully used in concrete without disturbing its durability and strength properties.
