Physical Properties of Gypseous Soil after Gypsum Removal using EDTA Solution
Tikrit Journal of Engineering Sciences, 2018 The main structural problem in construction on gypseous soils is due to the melting of the gypsum when exposed to water. This may be creating voids in the soil leading to rearrangement of the soil structure and moving the soil particles to more stable ...
