Description

Rust-resistant structure of paining of reinforcing bar for concrete

Technical Field

The utility model relates to a rust-resistant structure of paining of reinforcing bar for concrete.

Background

The steel bar is rusted due to two reasons, namely, a steel bar protective layer is carbonized, when the non-compact concrete is placed in the air or in an environment containing carbon dioxide, calcium hydroxide in the concrete reacts with the carbon dioxide due to the invasion of the carbon dioxide to generate substances such as calcium carbonate and the like, the alkalinity of the substances is gradually reduced or even disappears, the substances are called as the carbonization of the concrete, and the content of chloride ions is only 4-6 mg/L of the content of chloride ions, so that a passivation film of the steel bar can be sufficiently damaged, the steel bar is passivated, the steel bar is rusted under the action of water and oxygen, or under the combined action of the two reasons, the steel bar is gradually rusted, the rusty steel bar is continuously expanded in volume, cracks are generated on the concrete, the steel bar is continuously rusted, and a reinforced concrete member loses bearing capacity.

One non-patent document is 'corrosion and protection of steel bars in concrete', the author is Tian Yu, and in the scientific and technical information, construction and engineering, 2011 15, the document expresses the reason of corrosion of steel bars in concrete, wherein a passive film is damaged when chloride ions are gathered to a certain degree, so that the steel bars are corroded, and the sources of the chloride ions are mainly two, namely the chloride ions doped in the process of mixing concrete and the external chloride ions permeate into the concrete through concrete pores, but the problem of corrosion of steel bars in a concrete structure is the importance of threatening the durability of the concrete structure, so that the loss caused by corrosion damage needs to be reduced as much as possible.
