The invention relates to a visual concrete-structured reinforcing steel corrosion test device and an operation method of the visual concrete-structured reinforcing steel corrosion test device; the visual concrete-structured reinforcing steel corrosion test device disclosed by the invention comprises a test box and a box cover which can be covered with the test box in a sealing manner; both the test box and the box cover are made of a transparent material; transparent guide plates are arranged in the test box; the transparent guide plates are arranged in a staggered manner, so that the internal space of the test box is separated into zigzag spaces; a reference electrode fixing base for fixing a reference electrode and a test piece fixing base for fixing a test piece are arranged in the test box; the installation position can be changed through the test piece fixing base; the reference electrode and the test piece are connected with a test apparatus through a monitoring connection line respectively. When the visual concrete-structured reinforcing steel corrosion test device is used, the test piece fixing base fixed with the test piece is put at a proper position; then, a test solution is poured into the test box; different concrete conductivities are simulated by adjusting the purity and the liquid path zigzag length of the test solution; different concrete gap liquid hydrogen ion concentration pH values are simulated by adjusting the contents of calcium hydroxide, potassium hydroxide and the like in the test solution; the test method disclosed by the invention is simple; parameters are convenient to adjust.
Description
technical field [0001] The invention relates to the technical field of concrete structure steel bar corrosion test, in particular to a concrete structure visual steel bar corrosion test device and an operation method thereof. Background technique [0002] Reinforced concrete is widely used in modern civil engineering. While meeting the requirements of structural bearing capacity, the durability of concrete cannot be ignored. Among the many factors affecting the durability of concrete, the corrosion of concrete steel bars is the main factor affecting the durability of concrete. The corrosion of steel bars causes the performance of structural components to decline, and the bearing capacity of components decreases, thus posing a threat to the long-term applicability of the entire structure. Steel bar corrosion in concrete is a complex process, including the electrochemical reaction of steel bar corrosion and the physical action process of rust expansion force. Corrosion of ste...
