The comprehensive testing method for the performance of new environmentally friendly materials for civil engineering according to claim 8, characterized in that: Step S3 specifically includes: Freeze resistance test: the new environmentally friendly material is sent to a test module (301) with a temperature control device and then subjected to a freeze-thaw cycle test. The number of cycles and the temperature range are set. After each cycle, the appearance change of the sample is checked and the mass loss and strength loss are measured. Permeability test: the new environmentally friendly material is sent to a test module (301) equipped with a permeability test device, a certain water pressure is applied to the sample, and maintained for a certain period of time, and the amount of water that passes through the new environmentally friendly material sample is measured to evaluate the permeability performance; Environmental simulation test: The new environmentally friendly material is sent to a test module (301) with an environmental simulation function. The test module (301) can accurately control environmental parameters such as temperature, humidity, light, and pH. The temperature control range is -20°C to 60°C, the humidity control range is 30%-95%, and the light intensity can be adjusted between 0-10000 lux. The pH can be simulated by a spray or immersion system to simulate different acid and alkaline environments such as acid rain and groundwater, so as to comprehensively test the durability of the material under various harsh natural environments and special working conditions.
