Description

technical field [0001] The invention belongs to the field of building materials, in particular to a simulation device for acid rain environmental corrosion of cement-based materials. Background technique [0002] Acid rain is a global environmental problem today. Ca(OH) in cement-based materials under acid rain erosion 2 , C-S-H and other hydration products are prone to decomposition and expansion, resulting in a significant reduction in the mechanical properties of cement-based materials or even a complete loss, especially the reinforcement in the structure is easy to lose protection and accelerate corrosion. The material structure brings great safety hazards. Therefore, as far as engineering applications are concerned, the current civil engineering community urgently needs to ascertain the corrosion damage degradation process and damage degradation mechanism of cement-based materials in acid rain environments. [0003] To find out the acid rain environment corrosion dam...

AI Technical Summary

Problems solved by technology

[0004] 1. The interaction of one or more environmental conditions such as acid rain erosion, rainfall erosion, mechanical load, and solar ultraviolet radiation aging is not considered. The simulated environmental conditions have a single function and a narrow scope of application, which is far from the actual environmental conditions of the project.

[0005] 2. Low degree of intelligent control, inaccurate control of environmental parameters provided, high labor intensity, etc.

However, this type of simulation device still has problems such as the single function of the simulated environmental conditions, narrow scope of application, and far from the actual service environment of the project.

[0007] In short, single function, narrow scope of application, low degree of intelligent control, and the simulated environmental conditions are far from the actual service environment conditions of the project. These are the main problems existing in similar simulation devices at present.

This is also the main reason why the material properties of the current laboratory research are out of touch with the actual application performance, so it is impossible to conduct in-depth research on the corrosion damage degradation process and damage degradation mechanism of cement-based materials in acid rain environments.
