    10/7/2014  Table of soundness test of aggregate 9. Discussion Conclusion: Since no. of cycles is 10 and re-agent used is Na2So4 so the maximum percentage loss is 25%. When the percentage loss is greater than 25% then, this test shows that aggregate undergoes weathering process which ultimately decreases bearing strength.

  • Sulfate Soundness Test - Pavement Interactive

    The soundness test determines an aggregate’s 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, which simulate ice crystal formation (Figures 1 ...
