Galvanized and epoxy paint rebars in concrete structures as additional protection against their corrosion


Adriana de Araujo; Zehbour Panossian


Abstract:

The coating of carbon steel rebars in reinforced concrete structures is a technique for corrosion protection widespread in many countries. It is usually adopted in works of great responsibility, especially those which the structure is exposed to a strong aggression environment. As with other protection techniques, it is suitable for structures with restricting of maintenance and in precast concrete (colored or non colored concrete). In general, the coating is done by hot dip galvanization or by applying epoxy paint (Epoxy Bond Fusion - FBE). These two types of coating are presented in this paper, being important parameters related to production and capacity corrosion protection provided to concrete structures discussed;
