Abstract

The invention provides an exosmosis electricity acceleration type steel bar corrosion testing device and a building method thereof. The device comprises a strain collecting instrument, a test piece, a stainless steel piece, an electrolyte solution and a power supply, wherein the test piece is connected with the strain collecting instrument through a lead, the stainless steel piece is arranged on the test piece, the electrolyte solution is set on the test piece, and the power supply is used for supplying power to the stainless steel piece and the test piece; and the test piece is a concrete test piece internally provided with steel bars adhered with strain gauges, the strain gauges are electrically connected with the strain collecting instrument through leads, and a groove is preformed in the top of the test piece and is used for containing the electrolyte solution. The building method sequentially comprises the steps of processing the steel bars, producing a concrete pouring mold, producing the test piece, and assembling the test piece with the power supply and the strain collecting instrument. According to the device, the corrosion of the steel bars is accordant with a natural corrosion rule, the corrosion cracking of reinforced concrete is accordant with practical conditions of engineering, and corroded parts and corrosion degrees of the steel bars can be detected.

Description

technical field [0001] The invention belongs to the technical field of durability test methods for reinforced concrete, and in particular relates to a device for testing the corrosion of steel bars accelerated by exfiltration and a construction method. Background technique [0002] The corrosion of steel bars in concrete is a slow process in natural environments, and it will take at least several years for reinforced concrete members to have durability problems, which will make research difficult. Therefore, how to accelerate the corrosion of steel bars in concrete in a laboratory environment and Accurately simulating the real state of corrosion of steel bars in concrete is a problem faced by experimental research, and the corrosion monitoring of steel bars becomes more difficult due to the inhomogeneity of steel bar corrosion. [0003] At present, the commonly used steel corrosion detection methods mainly include acoustic wave detection method, infrared thermal imaging meth...
