Testing device for studying durability of concrete structure in corrosive environment

Abstract

The invention belongs to the technical field of concrete structure test devices, and discloses a test device for studying durability of a concrete structure in a corrosion environment, the test device comprises a test box, a material supporting assembly, a retracting and releasing assembly and an aeration assembly, a mounting frame is fixed at the top end of the test box, and a first partition plate and a second partition plate are arranged in the test box; the first partition plate and the second partition plate divide the interior of the test box into a first test cavity, a second test cavity and a third test cavity, and the lower ends of the front surface walls of the first test cavity, the second test cavity and the third test cavity are all connected with discharging pipes. When a test is carried out, only the concrete structural member to be tested needs to be placed on the material supporting assembly, then the material supporting assembly is lowered to the position below the liquid level of liquid in the test box through the collecting and releasing assembly, the change of the concrete structural member to be tested is observed, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of concrete structure test devices, and in particular relates to a test device for research on the durability of concrete structures in a corrosive environment. Background technique [0002] Concrete structures in corrosive environments are susceptible to corrosion (sulfate corrosion, seawater corrosion, etc.), resulting in a decline in their performance, which directly affects the safety and durability of concrete structures. Compared with ordinary environments, concrete structures, especially reinforced concrete structures, are The performance degrades rapidly during service in a corrosive environment, and the impact of the corrosive environment on the durability of concrete structures is a problem that needs to be studied and solved. One is the field exposure test method, and the other is the indoor accelerated test method. The former uses the real field environment as the corrosive environment, which has...
