Description

Technical Field

[0001] The utility model belongs to the technical field of concrete performance testing equipment, in particular to a cast-in-place concrete waterproof and durability testing mould. Background Art

[0002] Concrete, as a primary building material, is widely used in construction projects. The durability of concrete depends largely on its permeability, which refers to the ease with which gases, liquids, or ions penetrate, diffuse, or migrate through concrete under the influence of pressure, chemical potential, or electric fields. During construction projects, irregular cracks can easily develop in the cast-in-place concrete layer of a roof, leading to water leaks and impacting the usability of the building. The appearance of cracks is often related to factors such as the concrete mix ratio and the external environment. Due to differences in raw materials and their mix ratios, as well as external environmental factors, the water resistance of concrete is uncertain. Therefore, pre-construction testing of concrete water resistance is necessary. Conventional testing involves securing concrete specimens on a test platform and subjecting them to a water pressure shock. This method, where water is not collected, can lead to waste and contaminate the surrounding work environment. If sealing and protection are not performed properly, water seeping in from around the specimen can easily affect test data. Utility Model Content
