Description

Technical Field

[0001] The invention relates to the technical field of recycled concrete water seepage and adsorption detection, in particular to a recycled concrete specimen water seepage and adsorption detection system. Background Art

[0002] With the advancement of infrastructure construction, a large amount of construction waste is generated. For the sake of environmental protection and resource recycling, construction waste can be processed to make recycled aggregate concrete. By utilizing the porous and adsorbent properties of recycled aggregates, recycled concrete permeable products for sponge city construction can be developed. When studying recycled permeable concrete, it is necessary to continuously test the permeability and water absorption properties of the products to optimize the formula of recycled permeable concrete and to achieve the optimal solution for various properties of recycled permeable concrete.

[0003] According to the recycled concrete specimen water seepage and adsorption test system with announcement number CN117538237B, the test system includes a test box, a plurality of water outlet holes are provided on the bottom end surface of the annular water storage cavity of the annular rotating disk, and the dust storage box and the water pipe are both connected to the annular water storage cavity; the clamping assembly is located below the annular rotating disk, the clamping end of the clamping assembly clamps the recycled concrete specimen, the specimen support assembly is used to support the recycled concrete specimen at different height positions in the clamping end of the clamping assembly, and the first collection box is used to collect water seeping from the recycled concrete specimen.

[0004] With respect to the above-mentioned related schemes, the recycled concrete specimen is clamped by the clamping assembly, and the dust in the dust storage box is mixed with the water in the water pipe, so that the runoff of rainwater in more situations can be simulated, and the seepage water is collected by the first collection box, so that the water seepage and water absorption test of the recycled concrete specimen can be realized. However, it can only realize the water seepage and adsorption detection of recycled concrete specimens of a single size. Since there is a size effect in concrete materials, that is, specimens of different sizes will show different performances when subjected to force or environmental effects, therefore, only testing specimens of a single size cannot accurately reflect the performance of recycled concrete in actual engineering; secondly, the test results of a single size are only applicable to the specific size, while recycled concrete is used for structural components of different sizes in actual engineering, so the test results have limitations; in addition, the water seepage and adsorption performance are affected by many factors, and only testing a single size cannot comprehensively evaluate the performance of recycled concrete under various factors, and it is difficult to provide sufficient basis for engineering design and construction.
