Scope

This Standard specifies the sampling method, apparatus, test procedures, result
treatment method, etc. of using the rapid mortar bar method to inspect the alkali
reactivity of aggregate for railway concrete.
This Standard is applicable to evaluate the alkali-silicate reactivity of siliceous
aggregate; it is also applicable to the alkali-silicate reactivity of components in the
carbonate aggregate.
