Second, as the gypsum crystals begin to grow, they ‘lock’ themselves into surfaces that do not have a coarse enough profile for traditional cements to cling to. Gypcrete can be a loose and powdery deposit or a massive crystalline structure. The profile of a gypcrust outcrop can have three layers. The bottom layer is the sand rose horizon at the water table where gypsum develops as aggregates of crystals. The middle layer is composed of massive gypcrete cemented sand, which forms above the water table during evaporation from the capillary fringe; newly formed gypcrete will be hard, and will soften with age. The uppermost layer is usu… WebMineralogy and Geochemistry of Gypcrete, Khaldoun S. Al-Bassam and Ra'ad M. Dawood 64 INTRODUTION Gypcrete and gypsiferous soils are widely spread in Iraq.
