Abstract

The invention discloses a reinforced concrete corrosion test device which comprises a test box, an electrochemical workstation and a direct-current power supply. A high-concentration chlorine salt brine solution is contained in the test box, and an electrochemical reaction cathode steel bar plate and a reinforced concrete test sample are arranged in the test box and soaked in the high-concentration chlorine salt brine solution; the electrochemical reaction cathode steel bar plate makes good contact with the reinforced concrete test sample; the reinforced concrete test sample comprises concrete and a steel bar arranged in the concrete; the positive pole of the direct-current power supply is connected with the steel bar of the reinforced concrete test sample, and the negative pole of the direct-current power supply is connected with the electrochemical reaction cathode steel bar plate; the electrochemical workstation is used for testing the steel bar of the reinforced concrete test sample for an electrochemical test. The invention further provides a reinforced concrete corrosion test method. The device is high in controllability, easy to operate and accurate and reliable in result. The method is short in test cycle, convenient for test result analysis and high in accuracy.

Description

technical field [0001] The invention relates to the field of reinforced concrete corrosion research, in particular to a reinforced concrete corrosion test device and test method under the coupling action of stray current and brine. Background technique [0002] Stray current refers to the current flowing outside the designed or specified circuit, also known as "stray current". Stray current is essentially electrochemical corrosion, so anode corrosion is more serious. [0003] The life prediction of buildings has always been a popular research direction, and it is of great significance to society. Theoretically, reinforced concrete structures have both high compressive strength and high tensile strength due to their unique combination characteristics. Therefore, the theoretical service life of the reinforced concrete structure is longer, and it is the largest engineering structure used in actual engineering. However, in actual engineering, a large number of reinforced conc...

Problems solved by technology

At present, there is no device to conduct corrosion tests on reinforced concrete under the coupling effect of stray current-brine salt solution, so it is impossible to conduct research on reinforced concrete under the coupling effect of stray current-brine salt solution, which is not conducive to the staff to accurately grasp The corrosion of reinforced concrete under the coupling effect of stray current-brine salt solution cannot provide a theoretical basis for the improvement of the durability and life prediction of reinforced concrete under the coupling effect of stray current-brine salt solution, and there are potential safety hazards
