This process causes salt crystals to form in the aggregate's water permable pores. Crystal formation tends to create internal pressure and break the aggregate. After a specified number of cycles, aggregate samples are washed and sieved to determine their mass loss. Aggregates are separated into several size ranges and tested independently during the test. The final reported .
Test Procedure. Fine aggregates. Take a 1kg fine aggregate test sample. Arrange the IS sive in descending 10mm,,,, 600 microns, 300 microns, 150 microns and 75 microns. Now fill the sample to the highest sieve and sieve well for up to 10 minutes. After completion of sieving, then weigh the aggregates retained in each sieve note it down. Coarse aggregates. Take 1kg of .
