ASTM D4792-99
Historical Standard: ASTM D4792-99 Standard Test Method for Potential Expansion of Aggregates from Hydration Reactions
SUPERSEDED (see Active link, below)
1. 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
