Abstract

The issue of the limit of technical and economic optimization of dry building mixes compositions does not lose its relevance and remains one of the main and priority issues in the industry. One of the ways to solve this issue is to use the most advanced chemical additives that minimize the cost of mixtures while maintaining the characteristics of the products. This paper discusses the use of rheological additive REOLIN RA 120 to optimize the compositions of plaster mixtures based on gypsum binder. It is shown that the use of REOLIN RA 120 in gypsum compositions reduces the complexity of plastering by increasing the range of permissible water-solid ratio, reducing the consumption of dry mix and improving the surface texture. The algorithm of introducing the additive and its effect on the indicators characterizing the complexity of preparation, application, leveling of the solution and subsequent treatment of the plaster surface is described.
