ABSTRACT:
The preparation of gypsum parts (dihydrate calcium sulfate) with high mechanical strength is obtained with the aid of water layers with nanometric thickness. Calcium sulfate is used, dihydrate as well as hemihydrate, to obtain parts from these two materials, pure or mixed, especially to use in construction work, where the parts are prepared by compressing their slightly humidified powders.
