Durability Assessment of Hot Dip Galvanized Reinforcement Concrete
Treat the steel bars by hot dip galvanizing technology to prepare steel concrete specimen. Adopt artificial accelerated corrosion test to simulate the seawater corrosive environment in continuous immersion zone and tidal zone and carry out accelerated corrosion for the concrete bars. Add NaCl whose cement content is 1%, 5% and 7% respectively in the concrete specimen to improve the chloride ion content in the system and simulate the strong corrosion environment. This thesis examines the corrosion influence of chloride ion penetration on the ordinary bars and hot-dip steel bars. It also assesses the corrosion protection efficiency for hot dip galvanized reinforcement (HDGR) by half cell method and analyzes the test results.
