Hydrophobized clay gypsum

Abstract

Clay-gypsum binder is the main component for products and plaster coverings used in premises with dry climates. The raw material for producing clay-gypsum binder is sedimentary rock containing gypsum dihydrate and clay in an amount from5 to 30%. In order to expand the range and possibility of using clay-gypsum binder, it is hydrophobized by introducing synthetic resins. The purpose of the research presented in the article is to study the possibilities of increasing the softening coefficient of clay-gypsum binder by introducing thermosetting resins. As a result of the experiment, based on the methods of mathematical planning and statistical processing, a methodology for selecting the composition of the clay-gypsum binder was developed and the optimal content of thehydrophobing agentin the binder was determined.
