A device for testing the oxygen diffusion coefficient of concrete

Abstract

The invention discloses a concrete oxygen diffusion coefficient testing device which comprises a rectangular frame. A rectangular box body is installed on the upper wall face of the rectangular frame, the inside of the rectangular box body is of a hollow mechanism, the outside of the rectangular box body is a rectangular mechanism, a pair of partition plates is installed in the rectangular box body, a strip-shaped through hole is formed in the side wall face of the rectangular box body and located between the partition plates, a round through hole I is formed in the upper wall face of the rectangular box body, an air inlet pipe is installed in the round through hole I, and a round through hole IV is formed in the lower wall face of the rectangular box body. The concrete oxygen diffusion coefficient testing device brings convenience to people for concrete oxygen diffusion coefficient testing, is simple and convenient, makes the people conveniently, simply and clearly know the concrete quality and is high in practicability.

Description

technical field [0001] The invention relates to the field of concrete oxygen testing, in particular to a concrete oxygen diffusion coefficient testing device. Background technique [0002] Concrete, referred to as "concrete (tóng)": refers to the general designation of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the use of cement as the cementitious material, sand and stone as the aggregate; it is mixed with water (may contain admixtures and admixtures) in a certain proportion. [0003] Nowadays, concrete is widely used in engineering construction, but many projects cut corners and materials in order to save construction costs, resulting in serious problems in the quality of the floors after construction, so that people will have serious life safety hazards when they live or work. When the soil is used, people usually test it to check whether the quality is qualified, so as to p...

[0003] Nowadays, concrete is widely used in engineering construction, but many projects cut corners and materials in order to save construction costs, resulting in serious problems in the quality of the floors after construction, so that people will have serious life safety hazards when they live or work, so in the mix When the soil is used, people usually test it to check whether the quality is qualified, and to prevent the phenomenon of cutting corners. In view of this, the above-mentioned problems are studied, and this case arises
