The total sulphate content of aggregate is usually measured to assess whether the aggregate's contribution to the total sulphate content of a concrete mix will be low enough to prevent any deleterious effects.
subjecting the aggregate to cycles of immersion in a saturated solution of magnesium sulphate followed by oven-drying. The method is applicable to aggregate passing a 14.0mm test sieve but is retained on a 10.0mm test sieve. NOTE 1The majority of aggregates can be tested for soundness using this method.

Our experienced team will provide a thorough assessment and show you the aggregate properties. The range of physical, mechanical and chemical tests undertaken include:-Particle Size Distribution; Moisture Content; Particle Density and Water Absorption; Aggregate Impact Value; Sulphate and Chloride Content; Frost Heave; Resistance to Fragmentation
This document describes a test to determine the resistance of aggregates to disintegration from saturated sodium sulfate or magnesium sulfate solutions. The soundness test involves immersing coarse aggregate samples in a sodium sulfate solution for 24 hours, then drying and cooling them in cycles over 10 days.

SAMPLING Before conducting any test on aggregates, the first thing to do is sampling. A sample is a representative small portion from a larger whole or group of materials. ... 25 100 30 50 45 I 4.5 Acid soluble sulphate content When requested, the producer shall provide the acid soluble sulphate content of the aggregate determined in accordance ...
notably contribute to the problem of sulfate attack, which causes cracking and deterioration of concrete. Some aggregates can contain these sulfates and so can contribute to a reduction in durability. However, there is currently no standard test methodology to determine the sulfate content in the aggregates used to produce Portland cement concrete.
The oral test will be conducted on 5th and 6th June 2024. ... Size and shape of aggregates used in making concrete influence the workability of concrete. ii. As the water cement ratio in making concrete increases, the strength of concrete increases. iii. Maturity of concrete is independent of temperature at which it is cured.

considered in the selection of aggregates for which limits cannot be specified and determined by testing the aggregate itself in accordance with an accepted method of test. Guidance on chloride content is given in Appendix C. In general it will not be necessary to test each aggregate for all of the requirements specified in this standard.
