Steel plate bonding reinforcement application
Steel plate bonding reinforcement method has been widely used in strengthening engineering, its basic principle is using high performance epoxy adhesive bonded the steel plate to the concrete, so as to form a unified whole, to achieve the purpose of strengthening and enhancing the strength and stiffness of the original structure.

Reinforcement Rusting with Cracks on Concrete Constrution
In the absence of cracks, the alkaline environment causes the formation of an oxide film on the surface of the steel bar to prevent corrosion. After the crack appeared, the CO2 neutralized the alkaline environment and the oxide film disappeared.
