AbstractAbout the AuthorReferences
A general characteristic of the technology for strengthening building structures by the systems of external reinforcement with the use of polymer composite materials is presented. Requirements of the normative documentation for glue binders are given. Modification of epoxy resin and optimization of the composition of mixed hardener made it possible to develop compositions of glues, technological for using when making the external reinforcement systems. The effect оf reducing the viscosity of epoxy resins, when introducing in compositions of the single-layer and multi-layer carbon nanotubes, is revealed. Pilot tests of the developed compositions of glue binders in preparation volumes of 50–100 kg were conducted; their technological effectiveness was confirmed.
