Abstract

The paper considers the choice of methodology and quantitative determination of chloride ion content in concrete samples of bridge structures and other transport facilities, which are subject to increased requirements for corrosion resistance and durability. The violation of the passive film protecting the metal reinforcement in reinforced concrete is largely possible due to the penetration of aggressive chloride ions to the steel surface. Therefore, timely monitoring of chloride ion content in concrete samples of bridge structures is necessary to ensure the effective operation of these critical engineering structures.
