A cement solidification maintenance and resistivity measurement system under different temperature and humidity comprises a resistance measuring instrument, a cement solidification maintenance device, a copper sheet automatic limiting and spacing reading system, a vibration leveling system, a temperature and humidity control system and a PC computer system. And the PC computer system is connected with the resistance measuring instrument, the cement curing and curing device, the copper sheet automatic limiting and spacing reading system, the vibration leveling system and the temperature and humidity control system to realize control. Through cooperative use of the copper sheets, the box body and the like, the distance between the copper sheets, the temperature in the box body, the humidity and the test time can be adjusted, and meanwhile, different use requirements can be met by changing the mold and the size of the copper sheets and changing the geometric size of a cured object and the shape and the area of the copper sheets; the problem of inaccurate resistivity measurement of existing equipment is solved, the resistance change is monitored in real time, and the device has the advantages of high accuracy, stable performance and the like.
Description
technical field [0001] The invention belongs to the technical field of fly ash characteristic research, in particular to a cement solidified fly ash resistivity measuring device system that can effectively set and control different curing temperatures, humidity and curing time, and is suitable for quantitative scientific research tests of cement solidified fly ash. Background technique [0002] Fly ash is the ash produced by the incineration of domestic waste, which contains toxic components such as heavy metals and dioxins, and cannot be directly landfilled. At present, many treatment methods are to mix the fly ash with cement, and add a certain proportion of water to form fly ash cement. solidified, and then landfill. Cement fixes heavy metals through certain physical and chemical effects, reducing its toxicity and impact on the environment. Existing studies have shown that resistivity can quickly and non-destructively measure the toxicity risk of fly ash cement cured pro...
