Reinforced marine environment corrosion test methods for simulation

1 Scope

This standard specifies the method for evaluation of a simulated marine environment of reinforced concrete structures resistance to chlorine ion corrosion. This standard applies to reinforced concrete chloride ion corrosion resistance test. This standard consists of the following two methods, testing personnel can choose according to the actual conditions. Method A --- reinforced concrete resistant to chlorine ions in the corrosion test methods. By reaches a predetermined charge time to evaluate reinforced rot Corrosion performance. Under Method B --- marine environment reinforced Comparative Test methods of corrosion rate in concrete structures. By contrast with the steel bar corrosion Compare rates to evaluate the steel corrosion.
