Significance and Use
4.1 This test method provides a procedure for determining the compliance of steel slags and other materials with specifications, such as Specification D2940, that limit permissible expansion of base and subbase aggregates containing components subject to hydration.
1.1 This test method covers the determination of potential volume expansion of dense graded compacted aggregates that contain components susceptible to hydration and consequent volume increase, such as the free calcium and magnesium oxides that occur in some industrial by-products.
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 non-conformance with the standard.
