Determines the loss of mass when subjected to repeated wetting and drying with saturated sodium sulfate solution to approximate weathering of aggregate.

This Standard sets out the method for the testing of aggregates to determine their loss of mass due to disintegration when exposed to sodium sulfate solutions over repeated cycles of wetting and drying. The Standard furnishes information helpful in judging the soundness of aggregate subject to weathering action, particularly when adequate information is not available from service records of the material exposed to actual weathering conditions.
