AASHTO M 92 - Wire-Cloth Sieves for Testing Purposes AASHTO T 104 - Soundness of Aggregates by Use of Sodium Sulfate or Magnesium Sulfate ASTM C 88 - Soundness of Aggregates by Use of Sodium Sulfate or Magnesium Sulfate C. APPARATUS 1. Sieves Standard sieves conforming to AASHTO Designation M 92 are required.
The soundness test determines an aggregates resistance to disintegration by weathering and, in particular, freeze-thaw cycles. Description. The most common soundness test involves repeatedly submerging an aggregate sample in a saturated solution of sodium or magnesium sulfate. This process causes salt crystals to form in the aggregate pores ...
The soundness test repeatedly submerges an aggregate sample in a sodium sulfate or magnesium sulfate solution. This process causes salt crystals to form in the aggregates water permeable pores. The formation of these crystals creates internal forces that apply pressure on aggregate pores and tend to break the aggregate (Figure 1).
