Background In particular geographical areas such as saline-alkali soil, coastal areas, and the surrounding roads using deicing salts, concrete structures have long been in a highly saline-alkali environment. Chemical substances such as salt in the high-salt-alkali environment can erode the concrete, so that the structural performance of the concrete is changed, the compressive strength and durability of the concrete are reduced, and the service life and safety of the concrete structure are seriously affected. Therefore, the method has important practical significance in detecting the compressive property of the concrete in the high-salt-alkali environment. At present, most of the existing concrete compression-resistant detection equipment detects under a conventional environment, and the actual influence of a high-salt-alkali environment on concrete is difficult to accurately simulate.
