The Magnesium/Sodium Sulphate Test Set is designed for evaluating the soundness and durability of aggregates in accordance with EN 1367-2 and ASTM C88. The test simulates the effects of freeze-thaw weathering by repeatedly immersing aggregate samples in saturated sodium or magnesium sulphate solutions, allowing salt crystals to form within the aggregate pores.

The standard set includes a basket, stainless steel mesh, and hydrometer, while sodium sulphate and magnesium sulphate are available as optional accessories.

Aggregate Soundness Testing with Magnesium or Sodium Sulphate

The Magnesium/Sodium Sulphate Test Set is used to assess the durability and soundness of aggregates under standardized laboratory conditions. During the test, aggregate specimens are repeatedly immersed in a saturated sodium or magnesium sulphate solution and then dried.

As the solution crystallizes inside the aggregate pores, the expanding salt crystals simulate the internal stresses caused by freezing water. This accelerated weathering process helps evaluate the resistance of aggregates to disintegration and deterioration in service conditions.
