Annotation:

A method for obtaining a multifunctional additive for cement slurries by the method of low-temperature synthesis based on domestically produced materials is considered. The optimum temperature, composition and ratio of initial components are determined. The surfactant active properties of the additive such as contact angles, solubility in aqueous and non-aqueous solutions are investigated. It has been experimentally established that the additive has high plasticizing properties and, as a result of influencing the formation of the structure of the cement stone during its hardening, increases its strength.
