soundness test for aggregate

7 Lab Test on Aggregates that we Use in Concrete Construction!

Soundness Test of Cement What is soundness of cement? The ability of cement to retain its volume after it gets hardened is known as Soundness of Cement. That means the cement should be at minimum volume change after it gets hardened. The test conducted to identify the excess amount of lime in cement is known as soundness test of cement.

Jul 10, 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.
