The reduction in density of concrete made with waste foundry sand is expected, due to the physical characteristics of waste foundry sand which are fineness and porous. The more water absorption and fineness of the waste foundry sand (WFS) enhances the water requirement of concrete due to water absorption, which leads to decreased concrete density.
