1.Description:
The tester is applicable to the test method for determining the water permeability coefficient of permeable pavement bricks and permeable pavement panels as specified in GB/T25993-2010 "Appendix C - Test Method for Water Permeability Coefficient of Permeable Pavement Bricks and Permeable Pavement Panels". This instrument is mainly composed of a water tank, an electrical control box, sample fixtures, a platform, and other components. The sample fixture is suitable for samples with a cylindrical cross-section. The fixture ensures that during the test, the liquid can only pass through the pores on the surface of the sample without leaking from the edges of the sample.
2.Working principle
Permeability coefficient: The ability of a material to allow liquid to pass through under a certain pressure difference.
