ASTM C141-97

Standard Specification for Hydraulic Hydrated Lime for Structural Purposes

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.
