1. Scope | ||||||||||||||||||||||||||||
1.1 This test method covers the determination of change in height of cylindrical specimens from the time of molding until the mixture is hard. 1.2 This test method covers height change measurements at early ages for cementitious mixtures of paste, grout, mortar, and concrete. 1.3 This test method is intended for determination of changes in height that occur from the time of placement until the specimen is fully hard. These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects. 1.4 The values stated in SI units are to be regarded as the 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. 1.6 The text of this test method references notes and footnotes that provide explanatory information. These notes and footnotes shall not be considered as requirements of the test method. |
