# ASTM C289

Standard Test Method for Potential Alkali-Silica Reactivity of Aggregates (Chemical Method)

[Back to all techniques](/analytical-techniques/)

## 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-m sieve and be retained on a 150-m sieve.

1.2 The values stated in SI units are to be regarded as standard.
