To determine the durability of those weak aggregates, soundness test is specified in IS: 2386 Part-V.Carefully graded and weighed test samples of aggregates soak into either sodium sulphate or magnesium sulphate solution …
Several durability tests are available to quantify the weathering resistance of aggregates. In EU member states, the magnesium sulphate heptahydrate soundness test (EN 1367-2) [1] is used, whereas in most of the US and some other countries in the world, the ASTM C88 [2] sodium/magnesium sulphate soundness test is used. Both tests are …

Significance and Use 3.1 This test method provides a procedure for making a preliminary estimate of the soundness of aggregates for use in concrete and other purposes. The values obtained may be compared with specifications, for example Specification C33,
This test method furnishes information helpful in judging the soundness of aggregates subject to weathering action, particularly when adequate information is not available from service records of the material exposed to actual weathering conditions.
Sulfate Soundness Test. The soundness test determines an aggregate's resistance to disintegration by weathering and, in particular, freeze-thaw cycles.
This seems to be particularly true for aggregate toughness and abrasion resistance and durability and soundness. Toughness/abrasion resistance and durability/soundness tests for characterizing aggregate used in asphalt concrete were identified and evaluated, and those test methods that best correlate with field performance were determined.
4.2 Preparing Concrete Fine Aggregate: 4.2.1 Concrete fine aggregate consists of all concrete aggregate passing a 4.75 mm (No. 4) sieve, except for mineral filler. 4.2.2 Reduce the sample to test size shown in Tex-401-A. 4.2.3 Thoroughly wash the fine aggregate sample over a 300 m (No. 50) sieve, dry to constant mass in oven.
