AbstractAbout AuthorsReferences
The results of theoretical and experimental studies of the application of phospho-hemihydrate of calcium sulfate (PHH), waste of production of wet-process phosphoric acid from apatite concentrate under the hemi-hydrate regime, in the composition of dry building mixes, as a gypsum binder, are presented. The influence of replacing natural gypsum raw materials with anthropogenic PHH on the kinetics of hardening of solutions and physical-technical characteristics of samples of an artificial stone has been studied. Results of the X-ray phase analysis of the PHH composition are presented. It is shown that the phospho-hemihydrate of calcium sulfate can be used for producing dry building mixes without preliminary preparation
