Soundness Test for Aggregates Explained by devendrapadhiyar is a document available to read on EtoBox.
The sulfate soundness test involves submerging aggregate samples in a sodium or magnesium sulfate solution for 18 hours over 5 cycles to simulate salt crystal formation during freezing and thawing. The samples are weighed before and after each cycle to determine weight loss, with typical maximum losses ranging from 10-20% over the 5 cycles. Other soundness tests directly subject aggregates to freezing and thawing instead of the salt crystallization process.
