Research Progress on the Chloride Corrosion to Reinforced Concrete Structure and the Protection Measures

The safety of reinforced concrete structure is one of the main engineering problems of the 21st century. The durability of reinforced concrete structure has been a hot research topic in the field of building materials, which refers to that within a prescribed service life and under the influence of various environmental conditions, the reinforced concrete structure don't need the extra cost of reinforcement and maintain its normal security, usability and the ability of presenting an acceptable appearance. The steel bar corrosion is an important factor that affects the durability of concrete structure. In this study, the research progress on the chloride corrosion to reinforced concrete structure was introduced, and the protection measures were put forward, in order to provide beneficial references for the safeguard of building materials.
