(Specification)Standard Specification for Quicklime, Hydrated Lime, and Limestone for Selected Chemical and Industrial Uses
Standard Specification for Quicklime, Hydrated Lime, and Limestone for Selected Chemical and Industrial Uses
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.

3. Chemical Composition
3.1 The requirements for quicklime, hydrated lime, and limestone for the selected end uses are as shown in Table 1, and are
on the basis of the weight of sample taken at the place of manufacture, except as noted in footnote B after the requirement. In this
case, the requirement is on a moisture and carbon dioxide-free basis.
NOTE 1—Rags are cooked for the manufacture of paper in a digester under steam pressure with lime or with lime and soda ash. They are then washed
to eliminate as much of the noncellulose material as possible. A standard composition without rejection limits is specified for the reason that
