The invention relates to a method for testing the permeability resistance of concrete, and belongs to the field of tests. The method is characterized by comprising the following steps of: a, heating a test mold for concrete permeability resistance test to 65-70 DEG C in an oven; b, carrying out roll coating of hot wax on the periphery of a test block; c, quickly putting the wax coated test block into the test mold, wherein the diameter of the top of the test mold is greater than that of the bottom of the test mold; d, tightening an ejection device to press the test block into the test mold, and implementing wax sealing between the test block and the test mold; e, fixing the test mold filled with the test block on a tester platform by using bolts; f, opening a pressure water valve to pressurize the test block, and performing permeability resistance test; g, keeping the water pressure unchangeable after the test is completed, loosening screw caps of the ejection device by using a spanner, and extruding the test block out from the test mold by virtue of pressure water; and h, closing the pressure water valve, detaching the fixing bolts between the test mold and the tester platform, taking the test mold out, and thus completing the test.
