Abstract：According to hydrophobic pore-blocking agent mixed in concrete structure for the bearing platform of 2nd Humen Bridge,it improved workability,and increased mechanical property of concrete. It obviously decreased water absorption,chloride dif-fusion coefficient and the electric flux of concrete,and also increased the anti-permeability grade. Thereby,chloride ion penetration of concrete was decreased,and the steel corrosion wasn't occurred. In the process of engineering application,it had good application effect,improved the concrete structure durability.
