ASTM C1105-95(2002)
(Test Method)Standard Test Method for Length Change of Concrete Due to Alkali-Carbonate Rock Reaction
Standard Test Method for Length Change of Concrete Due to Alkali-Carbonate Rock Reaction
SCOPE
1.1 This test method covers the determination, by measurement of length change of concrete prisms, the susceptibility of cement-aggregate combinations to expansive alkali-carbonate reaction involving hydroxide ions associated with alkalies (sodium and potassium) and certain calcitic dolomites and dolomitic limestones.
1.2 The values stated in SI units are to be regarded as the standard.
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.
