DEVELOPMENT OF COMPOSITIONS OF PLASTER WATERPROOFING MIXTURE USING SULFOALUMINATE CEMENT

In this paper, the features of the development of plaster waterproofing mixtures using sufoaluminate cement (SAC) are considered. The main attention was paid to the selection of components that increase the strength, water resistance and reliable adhesion of the mortar to the substrate. The use of plasticizing additives Meflux 4930 and Melment F-10 contrib-utes to the intensification of hydration processes, the formation of the optimal structure of cement stone and the improve-ment of operational properties. It is shown that the regulation of the CAC content in the composition makes it possible to control the setting time and early strength of the binder, which is especially important when performing repair and restoration work. Optimization of the composition of dry mixes with fractionated quartz sand and modifiers helps to increase the durability of coatings and reduce the time of construction operations. The results obtained can be used to develop effective waterproofing compounds and improve their application technologies.
