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.
Alpha gypsum production by non pressure method in chloride salt solutions
Moldrzyk, Jan ; Gazdič,, Dominik (referee) ; Dvořák, Karel (advisor)
The work is focused on tht preparation of alpha hemihydrate calsium sulphate non pressure method of dehydration of gypsum in solutions of chloride salts. It deals with the verification methods developer for processing various types of available gypsum, particularly gypsum waste from the chemici industry. The resulting product is always assessed in terms of mineralogical, chemical and technological.
