ASTM International Standard Specification for Quicklime, Hydrated Lime, and Limestone for Environmental Uses ASTM C1529-06a

This specification covers lime and limestone productions and by-product alkaline materials suitable for environmental uses. Requirements for quicklime, hydrated lime, and limestone for the designated end uses are specified, and are on the basis of the weight of sample taken at the place of manufacture. Quicklime shall be free of unslakable residues and shall be capable of disintegrating in water to form a suspension of finely divided material. The amount of residue shall not exceed that agreed upon between the manufacturer and the purchaser (the residue is the amount of the material retained on a specified screen). The slaking rate for the specified quicklime should be matched to the requirements of the slaking equipment. Test methods such as chemical analyses, physical tests and basic factor test shall be performed.
