Влияние природы карбонатного сырья на образование синтетического гипса различной структуры в системе CaCO3 – H2SO4 – H2O

Abstract

In the course of experimental studies, it was found that the shape and size of the crystals affect the strength characteristics of the gypsum binder, as well as the filterability of the synthetic gypsum suspension, and the shape of the resulting crystals depends on the nature of the carbonate raw material used. It was found that the best filterability and strength characteristics are provided by crystals of prismatic and scaly forms of calcium sulfate dihydrate, obtained from insufficient lime and coagulation sediment of natural waters.
