Reduce Sulphate Content In Aggregates. Aggregates of specified size are subjected to cycles of alternate wetting in a saturated solution of either sodium sulphate or magnesium sulphate for 16 18 hours and then dried in oven at 105 to 110 0 c to a constant weight.After five cycles, the loss in weight of aggregates is determined by sieving out all undersized particles and weighing.

01-10-2006· However, the water soluble sulphate content of crushed clay brick was much higher than those of natural and recycled concrete aggregates where a value of 0.206 g/L was obtained. The soundness test results for natural and recycled concrete aggregates were similar with corresponding soundness values of 97.5% and 96.3%, respectively.

Highlights Soluble sulphates (from gypsum drywall) are a limiting factor in recycling of C&DW. Various samples were artificially prepared with different gypsum percentages. The pollution potential due to sulphate and heavy metals is studied. We analyze the correlation between solubility and leaching of sulphates. As a result, a limiting gypsum amount in a recycled aggregate is suggested.
29-12-2020· In particular, aggregation induced by water-soluble cyclodextrins and calixarenes, which are two classic of macrocycles with a hydrophobic cavity and a hydrophilic external surface, has attracted interest because these host molecules can form aggregates with guest molecules via various noncovalent interactions, including hydrophobic interactions, van der Waals forces, hydrogen bonds, …

Note 1—These test methods assume that the aggregate did not contain significant amounts of the water-soluble chlorides in question before the admixture was added. If significant amounts of these chlorides are known or suspected to be present, the aggregate shall be tested for these constituents according to these test methods and the proper corrections made.
