ASTM C5-10

Standard Specification for Quicklime for Structural Purposes

ABSTRACT
This specification covers all classes of quicklime such as crushed lime, granular lime, ground lime, lump lime, pebble lime, and pulverized lime, used for structural purposes. The quicklime shall conform to the chemical composition requirements specified. Quicklime shall be slaked and aged in accordance with printed directions of the manufacturer. The resulting lime putty shall be stored until cool. Test methods shall be performed for the chemical requirements, plasticity and residue requirements.
SCOPE
1.1 This specification covers all classes of quicklime such as crushed lime, granular lime, ground lime, lump lime, pebble lime, and pulverized lime, used for structural purposes.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
