The article presents the results of the fi nal series of tests on the study of ways to increase the corrosion resistance of reinforced concrete structures with primary protection in the form of an addition of acetone-formaldehyde resin ACF-75 and with secondary protection with a two-component resin Binder EP 11 Tikso. An analysis of the change in the adhesion strength of secondary protection elements with a concrete surface after exposure to sulfuric and nitric acid, as well as the eff ect of the presence of a preliminary primer on a concrete surface on the intensity of adhesion change is presented. Conclusions are drawn about the possibility of using a two-component resin Binder EP 11 Tikso as a secondary protection against corrosion destruction of concrete in the process of reinforcing reinforced concrete structures operating in environments containing sulfuric and nitric acids.
