ASTM C289 Standard Test Method for Potential Alkali-Silica Reactivity of Aggregates

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ASTM C289 testing. This test method involves the chemical determination of the potential reactivity of aggregate with alkalis in portland cement concrete as indicated by the amount of reaction between crushed and sieved aggregate with 1 N sodium hydroxide solution at 80°C for 24 hours. It is passed through a 300 m sieve and kept on a 150 m sieve.

When this test method is used to evaluate the potential reactivity of siliceous components in aggregate with alkalis in hydraulic cement concrete, it must be used in conjunction with other methods.

Reactions between sodium hydroxide solution and siliceous components in the aggregate have been shown to be related to the performance of some aggregates in concrete structures. Results of this testing method can be obtained quickly and can provide useful, although not completely reliable, data in all cases.

This standard does not purport to address all safety issues, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
