significance And Use:

4.1 This test method offers a means of comparing the relative linear shrinkage and coefficient of thermal expansion.

4.1.1 The material to be tested is placed in the mold in a fluid or... View More

scope:

1.1 This test method covers the measurement of the linear shrinkage during setting and curing and the coefficient of thermal expansion of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.

1.2 A bar of square cross-section is cast to a prescribed length in a mold that holds measuring studs that are captured in the ends of the finished casting.

1.2.1 The change in length after curing is measured and used to calculate shrinkage.

Note 1-Shrinkage determinations should not be made on sulfur mortars, since this test method cannot truly reflect the overall linear shrinkage of a sulfur mortar.

1.2.2 The change in length at a specific elevated temperature is measured and used to calculate the coefficient of thermal expansion.

1.3 This test method is limited to materials with aggregate size of 0.25 in. (6 mm) or less.

1.4 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.

1.5 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.
