Corrosion control of reinforcement forconcrete structures

Reinforcement technology for durable concrete

There are numerous examples, around the world, of spalling concrete found on structures within marine, inland urban and industrial environments. Clearly, there is a need to implement effective corrosion control methods in order to extend the long-term durability of steel reinforced concrete. Methods proposed for the corrosion protection of reinforcement do not, in any way, replace or usurp the importance of good quality concrete as the primary source of “barrier protection” against corrosive attack of steel reinforcement. What is proposed in this paper is a cost effective and site practical method, of improving corrosion protection of embedded reinforcement, before actual placement within a structure, i.e. prior to, during delivery to site and final installation. In short, prevention is better than cure.
