This document discusses a study on using fly ash to stabilize and solidify soils contaminated with heavy metals like lead, chromium, and other pollutants. The study shows that adding fly ash and quicklime to contaminated soils reduces leaching of heavy metals below regulatory limits by adsorbing and precipitating the metals. The treated soils also gain strength properties allowing reuse in construction. However, excessive ettringite formation from sulfates in the soil could cause swelling when wet. Adding b
