ASTM D4792/D4792M-13
(Test Method)Standard Test Method for Potential Expansion of Aggregates from Hydration Reactions
Standard Test Method for Potential Expansion of Aggregates from Hydration Reactions
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.
4.2 This test method can also be used to evaluate the effectiveness of aging or other treatments for reducing the expansive potential of such materials.
4.3 Test results have not been correlated with field performance, and values obtained do not necessarily indicate expansion that may occur in service conditions.
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 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.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 and health practices and determine the applicability of regulatory limitations prior to use.

Test Method D1883. Compaction is based on maximum density determination using Test Methods D698. To accelerate the
hydration reaction, specimens are stored in water at 70 6 3°C (158[158 6 5°F)5°F] for a minimum of 7 days.
