Alfa Gypsum Production Using Chloride Dust
Kalivoda, Karel ; Rovnaníková, Pavla (referee) ; Palou, Martin (referee) ; Kolář,, Karel (referee) ; Fridrichová, Marcela (advisor)
The aim of this doctoral thesis is to verify, using previously developed laboratory instruments, the possibility of a complete or partial substitution of currently used dehydration solutions of sodium chloride and calcium chloride by potassium chloride solution extracted from chloride dusts coming from cement production, using non-pressure method to produce alpha gypsum.
Preparation of high performance sulphate binder by nonpressure method
Urban, Karel ; Novák, Jan (referee) ; Dvořák, Karel (advisor)
Institut of Technology building materials and components in FAST VUT Brno is for several years engageding by research of unpressurized production of high sulphate binders and also by developing a dehydrating apparatus. This work follows on this research. The main aim of this work is to prepare the alpha calcium sulfate hemihydrate by method of dehydration in the various solutions the chloride salts of the same molal concentration in an innovative dehydration apparatus. Another aim is monitoring the influence dehydrating solutions on the basis of KCl, NaCl and CaCl2 on the properities of made gypsum.
