Significance and Use

When this test method is used to evaluate the potential reactivity of siliceous components in the aggregate with alkalies in hydraulic-cement concrete, it must be used in combination with other methods. Do not use the results of tests by this test method as the sole basis for acceptance or rejection for sources with regard to ASR.

Reactions between a sodium hydroxide solution and siliceous components in the aggregate have been shown to correlate with the performance of some aggregates in concrete structures. The results from this test method can be obtained quickly, and, while not completely reliable in all cases, they can provide useful data.

This test method can be employed as a quality control tool to periodically check samples from an existing source with an acceptable service history.

Scope

1.1 This test method covers chemical determination of the potential reactivity of an aggregate with alkalies in portland-cement concrete as indicated by the amount of reaction during 24 h at 80°C between 1 N sodium hydroxide solution and aggregate that has been crushed and sieved to pass a 300-μm sieve and be retained on a 150-μm sieve.

1.2 The values stated in SI units are to be regarded as 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. A specific precautionary statement is given in 5.7.1.
