ASTM C1529-06a

Standard Specification for Quicklime, Hydrated Lime, and Limestone for Environmental Uses

ABSTRACT
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.
SCOPE
1.1 This specification covers lime and limestone products suitable for environmental uses as shown in .
1.2 The buyer shall designate the use, as listed in , and may specify one or more of the type designations listed below .
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
