Standard Specification for Hydraulic Hydrated Lime for Structural Purposes

ABSTRACT
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.
SCOPE
1.1 This specification covers hydraulic hydrated lime for structural purposes.  
1.2 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.  
1.3 The values stated in inch-pound units are to be regarded as the standard.  
1.4 The following precautionary caveat pertains only to the test method portion, Section 10 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.
