Use of energetic by-products and other secondary raw materials for the alpha gypsum production
Moldrzyk, Jan ; Jiroušková, Kateřina (referee) ; Dvořák, Karel (advisor)
Thesis focus on the longterm research in an area of alpha gypsum production by non pressure method in chloride salt solutions production, which is researched by Institute od technology of building materials and components, Faculty of civil engineering for many years. The result of given research is non pressure equipment for alpha gypsum production. The scope of this research was to make a production of alpha gypsum more efficient through modification of the facility itself and through an optimalization of dehydration process. The scientific aim of this process was to compare an influence of dehydratation solutions of CaCl2, NaCl and KCl on the final product provided that molarity of solutions was at the same level.
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.
