ASTM C911-06

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.
SCOPE
1.1 This specification covers lime and limestone products suitable for the following chemical and industrial uses:
1.3 The buyer shall designate the use, as listed in , and may specify one or more of the type designations in .
1.4 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 limitations prior to use.
1.5 This test method covers the determination of the amount of free calcium oxide (CaO) in high-calcium hydrated lime capable of being hydrated by steam at atmospheric pressure.
