    Abstract

    This specification covers lime and limestone products that are suitable for chemical and industrial uses such as in waste acid neutralization, agricultural liming, soil stabilization, asphalt, flue gas desulfurization, drinking water softening, waste and wastewater neutralization, and wastewater treatment plant residuals stabilization. The required chemical composition of quicklime, hydrated lime, and limestone for each selected end use are on the bases of the weight sample taken at the place of manufacture. Quicklime should be free of unslakable residues and should be capable of disintegrating in water to form suspensions of finely divided material.
