Gypsiferous soils
Gypsiferous soils
(OP)
Hello
Can someone point me toward any free content about problems relatd to Gypsiferous soils for foundations ?
What paramater can be affected by the presence of gypsum deposits , especially for clayey soils ?
Can we find Anyhdrite in arid regions like deserts ?

RE: Gypsiferous soils
Thing is a wise client decided to plant trees in the desert very close to his foundations , and shower the soil with endless irrigation water. Soil consists of gypsiferous clays and or clayer soils with heave potential . Funny thing is all constructions consists of a lobby building only , and suffered fissures in the masonery only ( no damage to the structure ) . I am interested on the effect of gypsum and anhydrite on soil behavior , although there are many articles around in the net .

Additionally, all of these constituents will dissolve in water, thus changing the volume if sufficient water is available.

What about collapse potential ?

I sort of know what you mean by, "gypsiferous" soil. I just don't know whether, "gypsum" is truly the bad actor. I mean gypsum already has the water in mineral form. Now anhydrite could be a bad actor, just like oxidized pyrite can lead to a very mobile form of sulfur.

To anybody reading this thread, a bit of research on gypsum and its distinctions between carbonate mineralogy and its distinction with anhydrite may be helpful.
Gypsum is quite stable and it takes the kiln to clinker it to cement (well along with a few other raw ingredients).

I live in a semi-arid to arid environment and deal with the entire range of anhydrite to crystalline gypsum to diffused sulfates in soils and weathered rocks. The problems range from minor/moderate expansion in specific operations of soil stabilization to potentially severe collapse due to water solution. Whether water is just wetting or is moving through the soil/rock (and transporting minerals out of the system) is as important as the mineralogy AND crystal habit.
