The results of the first two series of studies of ways to increase the corrosion resistance of reinforced concrete structures with primary protection in the form of an additive of acetone-formaldehyde resin ACF-75 and with secondary protection with a two-component resin Binder EP 11 Tikso are presented. Studies have shown that the addition of ACF-75 leads to a significant increase in the strength of concrete. The results of laboratory tests have shown that the use of concrete with the addition of ACF-75 is unacceptable in reinforced concrete structures operating in environments containing sulfuric and nitric acids, without additional corrosion protection of the surface. In the course of the study, it was proved that the samples coated in three layers with Binder EP11 Thixo resin were resistant to a 5% solution of nitric acid.
