Estimation of the Filled Two-Component Cold Curing Polymer System Performance as a Coating for Protecting Concrete Surfaces from the Aggressive Environment Exposure

Abstract:

A filled two-component polymer cold curingsystem (FTCPS) is discussed in the article. To assess its corrosion resistance and durability, the indexes of reagent resistance were determined in accordance with the sorption method. What is optimal, since this value depends on the parameters of mass transfer, the intensity of the reaction, the size of the product, the duration of exposure to aggressive media and other factors. As aggressive media were taken: water, 5% hydrochloric acid solution, 25% aqueous ammonia solution, 10% sodium hydroxide solution, saturated sodium chloride solution. The exposure time was 360 days. Reagent resistance evaluation of the developed FTCPScompositionswas carried out on the basis of guidelines for determining the anticorrosive properties of protective coatings of concrete and laboratory test methods. Changes in the mass of the samples and their reagent resistance as a result of exposure to chemical reagents simulating an aggressive environment during operation were evaluated. The change in the index of reagent resistance in laboratory conditions did not go beyond the value of 0.80, which makes it possible to ensure reliable protection and operation of polymer-coated products under conditions of exposure to these aggressive environments.
