Abstract

The article presents the results of research on the positive effect of complex modification on the properties of heavy concrete. The study was carried out by reducing the content of binder (cement) and replacing it with metakaolin, due to which the hydrophysical characteristics were increased. It is noted that the positive results of the study make it possible to apply this composition in practice to obtain building structures with specified characteristics, and such structures can be operated under conditions of increased load and aggressive environment, in particular, in the construction of tunnels.
