(Test Method)Standard Test Method for Expansion of Hydraulic Cement Mortar Bars Stored in Water
Standard Test Method for Expansion of Hydraulic Cement Mortar Bars Stored in Water
SCOPE
1.1 This test method covers the determination of the expansion of mortar bars made using hydraulic cement, of which sulfate is an integral part.
1.1.1 Warning: Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
1.2 The values stated in SI units are to be regarded as the standard. Values 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.
