This specification covers all types of commercial hydrated lime such as: high-calcium, magnesium, or dolomitic-hydrated lime. By-product limes and slaked quick limes in dry, wet, or slurried form are also included.

Formerly under the jurisdiction of Committee C07 on Lime, this specification was withdrawn in March 2009 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

This specification covers all types of commercial hydrated lime such as: high-calcium, magnesium, or dolomitic-hydrated lime. This lime is used with pozzolans. The lime shall conform to the required physical and chemical limits: chemical factor, blaine fineness, and pozzolanic receptivity index. The following test methods shall be done: determination of calcium oxide, magnesium oxide, and carbon dioxide; calculation of chemical factor; blaine fineness; pozzolanic receptivity index; lime-pozzolan strength; and lime-pozzolan-aggregate strength and freeze-thaw resistance.

1.1 This specification covers all types of commercial hydrated lime such as: high-calcium, magnesium, or dolomitic-hydrated lime. By-product limes and slaked quick limes in dry, wet, or slurried form are also included.

1.2 This standard does not purport to address the safety problems 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.
