Standard Test Method for Potential Expansion of Steel Slag from Hydration Reactions by Autoclave
ASTM International , 01/01/2021
Pages: 5
1.1”This test method covers the determination of potential volume expansion of steel slags that contain components susceptible to hydration and consequent volume increase, such as the free calcium and magnesium oxides.
1.1.1”This method is based upon the Cement Autoclave procedure, Test Method C151/C151M, and the California Bearing Ratio procedure, Test Method D1883. This is an aggressive test that can detect both calcium and magnesium expansion potentials. The procedure is also a rapid method typically completed within 24”’h.
1.2”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 nonconformance with the standard.
Note 1:”Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4”This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
