ASTM C405-82(1997)

Withdrawn Rationale:

This practice covers estimating the consistency of thermal insulating cements, after mixing with a known amount of water. The consistency of a wet cement affects such properties as ease of toweling, wet adhesion, drying shrinkage, dry density, and thermal conductivity.

Formerly under the jurisdiction of Committee C16 on Thermal Insulation, this practice was withdrawn in February 2006 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

1.1 This practice covers estimating the consistency of thermal insulating cements, after mixing with a known amount of water. The consistency of a wet cement affects such properties as ease of toweling, wet adhesion, drying shrinkage, dry density, and thermal conductivity.

1.2 This practice estimates consistency of thermal insulating cements in terms of either percentage of deformation as described in Method A or inches of penetration as described in Method B.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety problems, 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.
