Standard Test Method for Potential Alkali Reactivity of Carbonate Rocks as Concrete Aggregates (Rock-Cylinder Method)
|Publication Date:||1 October 2019|
|ICS Code (Concrete and concrete products):||91.100.30|
This test method covers the determination of the expansion of a specimen of carbonate rock while immersed in a solution of sodium hydroxide (NaOH) at room temperature. The length changes occurring during such immersion indicate the general level of reactivity of the rock and whether tests should be made to determine the effect of aggregate prepared from the rock upon the volume change in concrete.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
