Assessment system and method of concrete chloride ion diffusion coefficient

The present invention discloses an assessment system of concrete chloride ion diffusion coefficient. The system includes a detection device, a processing device and a result output device. The detection device is used for detecting an initial current value of a concrete specimen, and an initial temperature, a finish temperature and a chloride ion penetration depth of an anode solution of the concrete specimen, and transmitting the results to the processing device; the processing device is used for receiving the initial current value transmitted by the detection device, comparing the initial current value with a preset threshold; when the initial current value is less than the preset threshold, the assessment result is directly delivered to the result output device; and when the initial current value is greater than or equal to the preset threshold, the processing device according to a preset algorithm calculates an assessment result by using an average value of the initial temperature and the finish temperatu
