[0002] Underwater non-dispersible concrete flocculants offer strong resistance to dispersion and good fluidity, enabling self-leveling and self-compacting underwater concrete. This prevents dispersion of cement and aggregate during underwater construction, while minimizing pollution to the construction waters. Underwater concrete containing flocculants, when suspended in water at a height of 0.3 to 0.5 meters, can achieve a compressive strength exceeding 70% of that of land-based concrete with the same mix ratio.

[0003] Before using underwater non-dispersible concrete, it needs to be tested for water permeability. Existing underwater non-dispersible concrete water permeability testing devices mostly use a booster pump to directly fill water into the concrete in the casting mold during the water permeation test, and then observe whether the molded concrete at the bottom of the casting mold is leaking after the water naturally penetrates. This detection method is slow, and it is necessary to maintain pressure during water filling to increase the test speed. To solve the above problem, a testing device for underwater non-dispersible material experiments is proposed to solve the above problem. Utility Model Content
