REBAR COATING

Reinforced concrete is inherently a valuable and near maintenance free construction material under normal conditions. Harsh environmental conditions such as exposure to seawater or deicing salts however can cause premature deterioration of the material. The expected service life of a reinforced concrete structure can be significantly reduced when choride penetrates to the concrete to the level of steel reinforcement when corrosion of the reinforcing steel is initiated , the products of corrosion expand and occupy a great volume than original steel and eventually cause cracking of the concrete. Once corrosion of the reinforcing steel has cracked the concrete , more chloride enters to attack the steel and deterioration of the reinforced concrete component or structure proceeds further pace. Premature deterioration of reinforced concrete structures due to corrosion of the reinforcing steel is of concern, worldwide.

Fusion bonded expoxy-coated reinforcing bars ( FBECR) have emerged as a viable and cost effective corrosion system for reinforced concrete structures. According to the original research , the epoxy coating is a physical barrier system that prevents moisture and chlorides from coming in contact with the Bor. Epoxy coating is also being regarded now as an electrochemical corrosion barrier which electrically isolates the bor by reducing the flow of corrosion current.
