Description

technical field [0001] The invention relates to a test device for testing the influence of temperature on the mechanical properties of materials or components in a cryogenic environment, in particular to a test device for testing the mechanical properties of reinforced concrete specimens at ultra-low temperatures. Background technique [0002] Large gas storage facilities need to work in cryogenic environments. For example, storage of ethylene requires an environment of -103.7°C, and storage of LNG (liquefied natural gas) requires an environment of -165°C. The exploration of outer space also involves ultra-low temperature environments, for example, the lowest temperature on the surface of the moon reaches minus 183°C. The extremely cold regions of the Arctic and Antarctic are also low-temperature environments, with the lowest temperature reaching -80°C. With the development of human society, the demand for energy and other materials has increased. For example, the mining o...
