【 摘 要 】

The article considers the possibility of using an additive based on amorphous aluminosilicates in the formulation of calcareous dry construction mixtures. Methods for the preparation of an additive, based on amorphous aluminosilicates, are considered. The results of the physicochemical analysis of the additive are given - the particle size, their distribution, and the oxide content in the additive composition. The mineralogical composition of the additive was studied using full-profile RFA with the help of the program DDMv.1.95d. The distribution and concentration of acid-base centers (active sites) on the surface of additive particles was revealed using the indicator method for the adsorption of indicators with different pKa values.
