Abstract

The paper presents the results of a study of the peculiarities of structure formation when adding complex silica-carbonate nanomodifying additives to Portland cement. The conducted research indicates that the modification of cement systems with complex organosilicate-carbonate additives leads to the directed formation of low-alkali hydro-silicate phases such as scawtite. These phases not only contribute to strength synthesis but also influence the micro-reinforcement characteristics of the cement matrix and the rheological properties of concrete mixes. The obtained high-strength matrices based on Portland cement systems modified with these additives can serve as the foundation for restoration and repair plaster and concrete materials used in emergency and urgent conservation work on cultural heritage sites during times of military conflict.
