Description

Technical Field

[0001] The utility model relates to the technical field of concrete performance testing, in particular to a concrete permeability test mould. Background Art

[0002] Concrete is a multiphase, inhomogeneous, porous composite system. When there is pressure, concentration and potential difference on the relative surfaces, material migration will occur. Since hydraulic structures such as dams, canals, culverts and submarine tunnels, once the anti-seepage performance does not meet the requirements, it will cause engineering accidents such as pollution and leakage. Permeability is the most important indicator to measure the durability of concrete. The permeability of concrete refers to the difficulty of gas, liquid or ion to penetrate, diffuse or migrate in concrete under the action of pressure, chemical potential or electric field. Commonly used concrete permeability test methods include: water permeability method, air permeability method, chlorine pool immersion method and electrical quantity method.

[0003] The existing test mold requires manpower to move the concrete blocks into the mold when in use, which is time-consuming, labor-intensive and highly dangerous. In order to ensure the accuracy of the test data, the concrete blocks need to be close to the inner wall of the mold, which makes it difficult to remove the concrete blocks after the test is completed. Therefore, a concrete permeability test mold is needed to solve the above problem. Utility Model Content
