ASTM-D4792 › Historical Revision Information
Standard Test Method for Potential Expansion of Aggregates from Hydration Reactions
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
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 SI units are to be regarded as the standard. The inch-pound units in parentheses are for information purposes 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.
Significance and Use
This test method provides a procedure for determining the compliance of steel slags and other materials with specifications, such as Specification D 2940
This test method can also be used to evaluate the effectiveness of aging or other treatments for reducing the expansive potential of such materials.
Test results have not been correlated with field performance, and values obtained do not necessarily indicate expansion that may occur in service conditions.
