Historical Standard: ASTM C1148-92a(2002) Standard Test Method for Measuring the Drying Shrinkage of Masonry Mortar
SUPERSEDED (see Active link, below)
ASTM C1148
1. Scope
1.1 This test method covers the measurement of unrestrained drying shrinkage of masonry mortars.
1.2 This test method is applicable to Specification C270 Type N, Type S, and Type M mortars under the property or proportion specifications. Due to the tendency to damage lower strength specimens during demolding, it is not applicable to lower strength mortars, such as Type O mortars.
1.3 This test method is intended for research purposes only.
1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only.
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.
