bottom ash from thermal power plants, and quarry dust have signifi cant potential for use as fi ne aggregates in concrete (Dhir and Paine 2010; Mullick 2012).

For example, acid rain is observed, intensity of heat increases due to the presence of greenhouse gases, and death of fishes and other aquatic animals in surface waters occurs. Cement factories and mining operations in limestone quarry sites may release large volumes of dust into the air, which further exacerbate environmental pollution. 21.3.3.
