Abstract

By chlorine salt and carbonization under the combined action of simulated concrete pore solution in determination of the natural potential of the reinforced method of the influence of basicity of chloride contaminated concrete critical NO2-/Cl- molar ratio.Results show:The increase of pH value or NO2-/Cl- molar ratio in concrete simulated pore solution can inhibit the corrosion of reinforcing steel bar;The NO2-/Cl- molar ratio of molar ratio less than the critical NO2-/Cl- mole ratio of the actual concrete is suppressed in the concrete simulated pore solution;The pore solution simulation has the concrete carbonization, corrosion inhibition required NO2-/Cl- molar ratio is 3 times of ordinary concrete carbonation.
