Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a test simulation chamber for fly ash-mixed concrete that can simulate underground environments. Background Technology

[0002] The fly ash concrete test simulation chamber, which can simulate underground environments, is a high-precision test device designed specifically for studying the performance evolution of fly ash concrete in complex underground environments. Its core function is to reproduce typical underground working conditions through controllable environmental parameters, including temperature and humidity fluctuations, groundwater chemical erosion, wet-dry cycles, micro-pressure changes, and long-term alkaline curing environments, in order to evaluate the impact of different fly ash contents on the durability, mechanical properties, and microstructure of concrete.

[0003] Existing concrete test simulation chambers can simultaneously reproduce temperature, humidity, groundwater chemical erosion, hydrostatic pressure, and wet-dry cycles, closely matching the actual burial depth environment of tunnels and pipe corridors. However, the temperature and humidity control system of the simulation chamber adopts uniform temperature control throughout the chamber, which cannot simulate gradient changes in the vertical or horizontal direction. Existing technology arranges multiple heating or cooling plates in the vertical direction of the chamber and controls the temperature gradient through PID algorithm, combined with a fogging system to achieve the humidity gradient. However, the temperature adjustment of the multi-layer heating or cooling plate system is usually fixed at a fixed level, making it difficult to quickly and accurately adjust the temperature of a specific height area according to the test requirements.
