ASTM C1489-01

Standard Specification for Lime Putty for Structural Purposes

ABSTRACT
This specification covers lime putty products made from hydrated lime or quicklime products. Lime putty is suitable for use in masonry, plaster and stucco applications. The hydrated lime or quicklime products used to make lime putty shall be tested and shall conform to the chemical composition, plasticity, residue, soaking period, popping and pitting, and density requirements specified.
SCOPE
1.1 This specification covers lime putty products made from hydrated lime or quicklime products. Lime putty is suitable for use in masonry, plaster and stucco applications.
1.2 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.
