Sulfate Soundness Test - Pavement Interactive

The soundness test determines an aggregate's resistance to disintegration by weathering and, in particular, freeze-thaw cycles.. Description. The most common soundness test involves repeatedly submerging an aggregate sample in a saturated solution of sodium or magnesium sulfate. This process causes salt crystals to form in the aggregate pores, which simulate ice crystal formation (Figures 1 ...

Analysis of total chloride content in concrete - ScienceDirect

It is clear from the figure that the BS total chloride limit of non-heat curing and made with sulphate resistance cement is going to be violated at mixtures with higher w/c ratios. Hence, the limits of total chloride content in concrete could be violated even though the limits of chloride content for mix ingredients are satisfied.
