Description
technical field [0001] The invention relates to the technical field of concrete durability test equipment, in particular to a concrete dry-wet cycle erosion test machine. Background technique [0002] Corrosion resistance is an important index reflecting the durability of concrete. At present, the research on the anti-corrosion performance of concrete mainly focuses on the coupling corrosion of concrete by sulfate corrosion, chloride ion corrosion, compound salt corrosion, and dry-wet cycle and the above-mentioned corrosive substances. Studies have shown that when subjected to chemical erosion, the water level change zone of concrete corrodes the fastest and deteriorates the most. Most of the existing indoor accelerated corrosion tests are aimed at the changes of temperature, humidity, water level, corrosive liquid type and concentration in the test chamber within a certain period of time to study the durability of concrete. Correlation studies bring a lot of volatility. ...
