Abstract
The invention discloses a sample preparation device of a test piece used for an electrochemical corrosion resistance test. The test piece is in a cylinder state, the sample preparation device comprises a test assembly, a top cover assembly and a bar reinforcement fixation assembly, the top cover assembly is fixed at an upper end of the test assembly, and is adapted to the test assembly; a throughhole used for passing through a bar reinforcement is arranged at the center of the top cover assembly, the bar reinforcement fixation assembly is fixed at the through hole, and is used for sleeving one end of the bar reinforcement; and the test assembly, the top cover assembly and the bar reinforcement fixation assembly are coaxially arranged. The test piece prepared by the sample preparation device cannot generate problem of random displacement of the bar reinforcement, the distance between the bar reinforcement and the outer wall and bottom of the test piece accords with the set requirement,incomplete maintenance of the produced test piece during a maintenance process cannot be generated, and the device is suitable for high diminishing / slow setting capability of a corrosion inhibitor and low viscosity of a mortar mixture.
Description
technical field [0001] The present application relates to the field of electrochemical tests of steel bar rust inhibitors, in particular to a sample preparation device for test pieces used in electrochemical anti-rust performance tests. Background technique [0002] Deterioration of concrete durability caused by corrosion of steel bars occurs from time to time. Reinforced concrete structures serving in coastal areas, underground spaces, and high-chlorinated areas are almost always subject to damage caused by chloride ion intrusion. In order to prevent the corrosion of steel bars in concrete by chloride ions in the environment, one of the most effective methods is to add a steel bar rust inhibitor when producing concrete to delay or eliminate the damage to steel bars by chloride ions. [0003] Whether the steel rust inhibitor has anti-rust effect needs to be evaluated by the test results. Compared with other methods for detecting the anti-rust effect of anti-rust agents, the...
