[0002] As is well known, in a sulfate environment, the coupling of dry-wet cycle conditions in concrete is often encountered in the actual environment. The damage speed of sulfate erosion coupled with dry-wet cycle conditions to concrete is relatively fast. For the study of concrete sulfate erosion tests, most researchers use the original manual handling method for specimens. In one cycle, first, the concrete specimens are taken out of the sodium sulfate solution and dried in the air, then carried to the oven for drying, and finally, the specimens are taken out for cooling and then put back into the sodium sulfate solution for soaking again and again. Repeatedly handling the specimens will cause artificial damage to the specimens, resulting in the lack of accuracy and reliability of the test results.

[0003] A concrete sulfate dry-wet cycle test device with the Chinese utility model application number CN202120518466.6 is convenient for handling specimens, and the accuracy and reliability of test results are improved. However, it is not convenient to place specimens and transfer baskets during use, and it is relatively inconvenient during use. Therefore, we propose a concrete sulfate dry-wet cycle test device to solve the above problems. Content of the Utility Model
