This test method covers the determination of the expansion of mortar bars made using hydraulic cement, of which sulfate is an integral part. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM C1038 for Expansion of Hydraulic Cement Mortar Bars Stored in Water.
