This specification covers hydraulic hydrated lime for structural purposes. Hydraulic hydrated lime may be used in the scratch or brown coat of plaster, stucco, mortar, or in Portland-cement concrete either as blend, amendment, or admixture. The hydraulic hydrated lime shall conform to the chemical composition requirements for calcium oxide, magnesium oxide, silica, iron oxide, aluminum oxide, and carbon dioxide. The sample shall be subjected to the following test methods: chemical analysis; fineness; normal consistency; time of setting; autoclave expansion; and compressive strength.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers hydrated hydraulic lime for structural purposes.

1.2 Hydrated hydraulic lime may be used in the scratch or brown coat of plaster, stucco, mortar, or in portland-cement concrete either as blend, amendment, or admixture.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4 The following precautionary caveat pertains only to the test method portion, Section 11 of this specification: 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
