Sulphate Content Testing. Sulphate attack is a chemical break down where sulphate ion attacks components of cement paste. Sodium Sulphate attacks calcium hydroxide and forms gypsum that becomes more than double the volume. Sulphate content testing performed in a laboratory can be used to assess sulphate content of samples retrieved from site.

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 and 2). The basic procedure is as follows (from Roberts et al., 1996 [1]):
