Description

Technical Field

[0001] The invention relates to the technical field of concrete testing equipment, and in particular to a concrete impermeability testing device and a testing method. Background Art

[0002] The term concrete refers to cement as a gelling material, sand and stone as aggregates, and water (which may contain admixtures and additives) mixed in a certain proportion and obtained by mixing. It is also called ordinary concrete. Concrete is an artificial building material widely used in construction. For some buildings, the concrete used in the building is required to have specific anti-seepage properties, so a concrete anti-seepage performance testing device is needed.

[0003] However, in the existing concrete impermeability test, the side of the sample needs to be wax-sealed to enhance the sealing performance after it is placed in the test mold to prevent it from affecting the test results. However, it is very easy to wear off the sealing wax during the step of pressing the sample into the test mold, which affects the sealing performance of the sample. In order to find out whether the sealing wax is intact or damaged during the test, the sample needs to be taken out, re-sealed and pressed into the test mold again. The sample may be damaged during the removal process, and re-making the sample will take up a lot of time, resulting in low test efficiency. In addition, after the test is completed, it is difficult to take the sample out of the test mold, which is easy to cause wear and even damage to the test mold, thereby increasing the test cost.
