Research of Physical and Mechanical Characteristics of Modified Adhesive Binders for Structural Reinforcement Systems of Building Structures

In construction practice, along with other technologies, methods of external reinforcement with polymer composite materials are widely used to strengthen structures. The authors developed modified epoxy-based adhesive binders to use in the construction of external reinforcement systems for building structures. The introduction of epoxy resin into the composition of multilayer CNTs in an amount from 0.001 to 0.01 wt. h. per 100 wt. h. leads to an increase in the adhesive characteristics of the adhesive, tensile and bending strength, while maintaining manufacturability. The temperature-time dependence of the creep of a reinforced concrete beam reinforced with an external reinforcement system based on the developed adhesive binder and carbon fabric is studied, and the obtained indicators are compared with an industrial analog. The constructed creep curves indicate the identical nature of the deformation process under loading at each temperature stage. At the same time, for a reinforced concrete beam strengthened with carbon fabric and RecARM-B glue, less deformability was noted in the studied temperature ranges.
