Abstract
AbstractClay gypsum as a natural material of sedimentary origin is widespread both in Russia and in the states formed in the post-Soviet space. In terms of energy intensity and manufacturability, the processing of raw materials into a clay-gypsum binder does not differ from the conditions of traditional processing of natural gypsum. Compared to lime or cement mortars, mortars based on gypsum binder have greater elasticity and plasticity. Such properties associated with the manufacturability of the application, such as workability and thixotropy, as well as the interval for maintaining the pot life of the mixture, are controlled by the introduction of modifying additives, the evaluation of the formulation of which was the purpose of the research, the results of which are presented in the article. The studies carried out have established that varying the recipe parameters make it possible to regulate both the strength and performance characteristics of mixtures based on gypsum plaster, as well as the manufacturability of their application.KeywordsModified binderGypsum plasterPlasterAdditivesGypsum binder
Highlights
Non-combustible gypsum-containing facings and plaster coatings in the event of a fire perform the function of a fire-retardant barrier, and at temperatures exceeding 180 ° C, dihydrate gypsum dehydrates, water evaporates, lowering the temperature of the fire effect and forming a protective vapor barrier [7-9]
Clay-gypsum raw material belongs to the group of sedimentary rocks
The properties of plaster mixes and plaster coatings depend on many factors
Summary
Complete systems have already become one of the traditional ways of introducing interior finishing works. The formed coating based on gypsum-containing plaster systems has a capillary-porous structure Such a structure allows, due to the processes of sorption of water vapor and the accompanying condensation of moisture in the form of thin films, allows you to regulate the humidity in the room. Interest in clay gypsum as a local binder and an analogue of gypsum manifested itself in the 50-70s of the last century, but the lack of a scientifically substantiated concept of its application made it impossible to effectively use the results obtained. Its use is supported by low production costs, large re-serves, non-energy-intensive processing technology, and properties that meet regulatory requirements [10–12]
