GB/T 31933-2015 Test method for the corrosion of steel bar embedded in concrete in chloride enviroment
Abstract
This standard specifies the evaluation method for the resistance of steel reinforcement in concrete structures to chloride ion corrosion in simulated marine environments.
This standard is applicable to the testing of the resistance of steel reinforcement in concrete to chloride ion corrosion.
This standard includes the following two methods, and test personnel can choose according to actual conditions.
Method A - Test method for the resistance of steel reinforcement to chloride ion corrosion in concrete. The corrosion resistance of the steel reinforcement is evaluated by the time it takes to reach a specified amount of electric charge.
Method B - Comparative test method for the corrosion rate of steel reinforcement in concrete structures in marine environments. The corrosion resistance of the steel reinforcement is evaluated by comparing its corrosion rate with that of a comparative steel reinforcement.
