产品介绍
"Soundness testing of aggregate requires repeated immersion cycles in sodium or magnesium sulfate solution, followed by drying. Rehydration of the salts simulates expansion of freezing water. Samples are then washed, dried and sieved to determine percentage of loss from original sample.","Sample Sieves holding aggregate specimens are stacked into Sieve Holders. The Holders are then immersed in Solution Buckets containing sulfate solution. The Refrigerated Circulator and Water Bath Tank need only be used if the temperature of the sulfate solution cannot be maintained at the specified 70°F (21°C)."," Coarse Aggregate Sample Sieves hold materials coarser than No. 4 for immersion. Sieves are 8in (203mm) diameter, half, full or special double-height stainless steel No. 10. Two or more double-height sieves may be required for large samples."
