AbstractAbout AuthorsReferences
A possibility of improving adhesion properties of gypsum binder systems when potassium-silicate cement is used in combination with organic substances-modifiers is considered. The influence of each selected component on basic properties of gypsum finishing mixes is defined. The addition of potassium-silicate cement increases the alkalinity of gypsum solution medium, intensifies processes of solution and colloiding of calcium sulfate hemihydrates, accelerates the setting time of the mass and reduces its water-retaining capacity. Gypsum binder with the addition of potassium-silicate cement has high adhesion strength to the ceramic base. Powder organic substances (modifiers) which make it possible to regulate processes of setting and hardening of gypsum solutions with the addition of potassium-silicate cement have been selected. High adhesion strength of mortars with an organic-mineral modifier to the ceramic base ensures the significant economy of the gypsum binder in the composition of finishing mixes.
