Special features of manufacture of acid fluoride-based artificial gypsum stone

Special features of manufacture of acid fluoride-based artificial gypsum stone. The article considers the possibility of obtaining gypsum stone from acid fluoride. The results of this work demonstrated that, on the base of freshly neutralised acid fluoride, one can produce artificial gypsum stone with high physico-mechanical characteristics, suitable for manufacturing Portland cement of a grade not lower than CEM I 42,5 N.
