Embodiment Construction

[0029] A method for testing the impermeability of concrete, which uses a press plate type concrete impermeability test device for testing, comprising the following steps:

[0030] 1) Make the test piece according to the standard; the test piece is a cylinder with a diameter and a height of 150mm.

[0031] 2) Place the test piece that meets the requirements in the lower metal chamber of the press-plate concrete impermeability test device, and the water outlet of the press-plate concrete impermeability test device is aligned with the center of the test piece.

[0032] 3) Install the upper metal pressure plate of the pressure plate type concrete impermeability test device on the fixed rod, and fix it tightly on the upper surface of the specimen to ensure that the water flow will not flow out from the bottom of the lower metal cavity during the test.

[0033] 4) Turn on the control switch and water pressure control valve of the pressure plate concrete impermeability test device, c...

Abstract

The invention discloses a method for testing concrete impermeability. The testing method is carried out by using a platen-type concrete impermeability test unit. The method comprises the following steps: manufacturing a specimen according to the standard; putting the satisfactory specimen in the lower metal cavity of the platen-type concrete impermeability test unit, wherein the water outlet of the platen-type concrete impermeability test unit is aligned with the center of the specimen; installing the upper metal platen of the platen-type concrete impermeability test unit onto a fixed link, and tightly fixing on the upper surface of the specimen, thereby ensuring that water can not flow out of the bottom of the lower metal cavity in the test process; opening the control switch and the hydraulic control valve of the platen-type concrete impermeability test unit, testing, and recording data; and processing the data obtained in the test, and making a judgment. The invention has the advantages of simple and convenient operation, and accurate and reliable test result.

Description

technical field [0001] The invention relates to a concrete performance test method, in particular to a concrete impermeability test method. Background technique [0002] Concrete is an important building material that is widely used today. The impermeability index of concrete is an important parameter to judge the quality of concrete. For the test devices used in the existing concrete impermeability test methods, see figure 1 and figure 2 . The impermeability test device includes a base 11 , a test piece mold 12 and a lower metal cavity 13 . The lower metal cavity 13 is arranged on the base 11 , the test piece mold 12 cooperates with the lower metal cavity 13 , and the concrete anti-seepage test block 16 is fixedly placed in the test piece mold 12 . An outer sealing ring 14 is arranged in the lower metal cavity 13, and a water outlet 15 is provided at the central position of the lower metal cavity 13. The outer sealing ring 14 is used to prevent water from flowing out ...
