Abstract: Chloride is the "main culprit" whose corrosion damages millions of bridges in the world, and it has caused heavy economic losses in various countries. Moreover the corrosion of chloride to the reinforcing steel bar is the main form of concrete structure damage. The research on deterioration mechanism shows that waterproofing and anticorrosive treatments must be carried out to the bridge in order to extend its service life. Hereto, the ZHONGHE 2000 series of waterproof materials had excellent waterproof and anti-corrosion properties will play an important role.
Key words: deicing chemical; concrete deterioration; reinforcing steel bar rustiness; waterproofing; anticorrosion; service life; ZHONGHE 2000 series waterproof materials
