The control of corrosion in reinforced concrete is an important aspect in conducting a successfullong-lasting concrete repair.
By far the greatest damage caused to concrete in structures is a result of corrosion exerted from within the embedded reinforcing bars to the surrounding concrete.
Corrosion is the natural process that occurs when the steel reinforcing bars within the reinforced structure are allowed to rust. As rust occupies a larger volume than the steel it surrounds it consequently exerts pressure on the encased concrete causing it to crack and damage the surrounding concrete surface.
Corrosion is allowed to propagate when aggressive materials that are harmful to steel reinforcing are able to penetrate the concrete surface and reach the steel reinforcement giving rise to what is known as either carbonation or chloride attack.
Corrosion control to reinforced concrete can be achieved using various techniques either through the application of anti-corrosion coatings that are applied to the surfaces of exposed concrete or the application of corrosion inhibitors that can be applied to external concrete surfaces or applied directly onto the embedded steel reinforcing bars, reinforcing bar corrosion barriers and protectors or the installation of embedded galvanic anodes.
All these control measures require specialist knowledge and expertise here at Churchill Concrete Technology we have the knowledge and expertise to undertake this type of work.
For corrosion control that stops the spread of damage across your concrete and provides protection against further damage occurring Churchill Concrete Technology should be your service provider of choice.
