Permeability test method for water blocking material and test body providing device for water permeability test

摘要

PROBLEM TO BE SOLVED: To allow a quantitative evaluation of the coefficient of permeability of a water shut-off material such as a vertical water shut-off material, on the basis of the followability to an aperture.SOLUTION: There is provided a method for a permeability test which considers the deformation followability of a water shut-off material, the method including the steps of: preparing a test piece obtained by filling a water shut-off material into a mold while a space holding material is being arranged in the mold; and removing the space holding material from the test piece and then running a permeability test.SELECTED DRAWING: Figure 1
