Sulfate Soundness Test

Gilson offers testing components for the Sulfate Soundness Test separately, allowing users to build the system that best meets their needs. Soundness testing of aggregates in sodium sulfate or magnesium sulfate solutions uses repeated soaking, drying and rehydration cycles to simulate damage to aggregates caused by natural freeze-thaw action. Salts are deposited in voids during soaking then crystalize upon drying and expand when rehydrated.
