This paper introduces the repair technique for damaged concrete structure with exposed reinforcing bars. By rust cleaning and painting reinforcing bars at the damages, a dense coating is formed on the surface of reinforcing bars to block contact of harmful media with reinforcing bars so as to protect reinforcing bars better. This construction technique exhibits good anti-corrosive properties and can avoid generation of drying shrinkage cracks and can be popularized in the projects of repairing bridge damages.
