Affects of gypsum in laboratory testing of soils
Affects of gypsum in laboratory testing of soils
(OP)
I'm inquiring if there is someone who knows what affect gypsum has to laboratory testing. For example if i run a proctor with significant gypsum content. What would be the effect to my test results if I dry back my moistures in high heat versus low heat.

Gypsum can also affect atterburg limits, though usually to a small degree.

I have also experienced problems with testing soils with gypsum for permeability, as the crystals appear to grow [with undisturbed samples it is not possible to determine the size of the crystals prior to testing] under saturated conditions impacting on the test.
