NANOMODIFICATION OF CEMENT SYSTEMS AS AN EFFECTIVE WAY TO IMPROVE THE QUALITY OF SPECIAL-PURPOSE BUILDING MORTARS

Abstract

The principles of compositional construction of nanomodified special-purpose mortars with improved performance characteristics are proposed, which involve optimization of the processes of structure formation not only at the nanolevel, but also at the micro- and meso-levels of their structure. The properties of waterproofing mortars based on cement systems modified with carbon nanotubes, which are distinguished by improved properties, are studied. The properties of optimized decorative plaster mortars based on white cement modified with nanocarbonate additives in the presence of a polycarboxylate superplasticizer are also considered, which are characterized by durability, low porosity, sufficiently high strength, crack resistance, which is achieved by controlling the processes of structure formation of artificial stone both at the nano-, micro- and meso-levels.
