Standard Test Method for Tensile Strength of Chemical-Resistant Mortar, Grouts, and Monolithic Surfacings

Significance and Use

It is recognized that chemical-resistant mortars, grouts, and monolithic surfacings are not usually under tension when in service; however, such data are useful for purposes of determining the rate of cure and other properties.

This test method is not recommended for mortars, grouts, and monolithic surfacings containing aggregate greater than ¼ in.


1.1 This test method covers the determination of tensile strength of cured chemical-resistant materials in the form of molded briquets. These materials include mortars, brick and tile grouts, machinery grouts, and monolithic surfacings. These materials shall be based on resin, silicate, silica, or sulfur binders.

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

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.
