(Test Method)Standard Test Method for Determination of Length Change of Concrete Due to Alkali-Silica Reaction
Standard Test Method for Determination of Length Change of Concrete Due to Alkali-Silica Reaction
SCOPE
1.1 This test method covers the determination, by measurement of length change of concrete prisms, of the susceptibility of a sample of an aggregate for participation in expansive alkali-silica reaction.
1.2 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.
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound values in parentheses are for information only.
