Abstract
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.
Description
Technical field
The present invention relates to civil engineering work with the impervious index test of water-tight concrete field; This impervious experiment is applicable to die trial measures the concrete impervious grade in water-tight concrete test block sclerosis back, the invention belongs to dividing an application of publication No. CN102042946A, application number 2009102068455 " concrete impermeability test being used die trial ".
Background technology
Detail drawing 1; This technology tradition is a bottom interior diameter 186mm with die trial, top inside diameter l76mm, and height is the frustum cone cylinder of 150mm; Correspondingly make concrete test block 2 by this die trial 1 size; Sclerosis reaches the boiling hot wax 3 of certain intensity rear perimeter edge, adopts special-purpose pressue device 4 that test block is pressed into die trial by two people then and treats to withdraw from pressure again after hot wax solidifies, and the die trial reverse up and down (the die trial bottom down) of taking out the band test block is installed on the impervious experiment porch 5; And fixing with bolt 7, plus-pressure water 6 is done the impermeability test of test block then.In this process owing to withdraw from that pressure is got die trial and because the die trial cooling strain; Very easily cause die trial and test block generation wherein to slide relatively; The layer of sealing with wax that oneself solidifies between the destruction can not guarantee the sealing between test block and the die trial; Thereby seep water between test block and the die trial when causing experiment, can not whole punching press test blocks of warranty test press water and the accurate impervious grade of measuring test block.Other rises and in die trial, takes out also inconvenience of test block after test finishes, and need reuse special-purpose pressue device and from die trial, extrude out test block.Like this operation effort, time-consuming, complex procedures and can not the warranty test result accurately.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of impermeability test method for concrete, easy disassembly, and good sealing effect has improved the precision of test findings, and is time saving and energy saving and reduced cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of impermeability test method for concrete is characterized in that a. is heated to 65～70 ℃ with concrete impermeability test with die trial in baking oven; B. hot wax roller coating is peripheral to test block; C. die trial is put in the test block of will waxing rapidly, and the top diameter of die trial is greater than base diameter; D. tighten jack unit test block is pressed into die trial, implement sealing with wax between test block and die trial; E., the die trial that test block will be housed is fixed by bolts on the test instrument platform; F. open pressure water valve pressurising test block, do impermeability test; G. test finishes, and the hydraulic pressure that keep-ups pressure is constant, unclamps the jack unit nut with spanner, and test block is extruded out by press water from die trial; H. the closing presure water valve is removed the set bolt between die trial and experiment porch, can take out die trial, and test finishes.
The invention has the beneficial effects as follows, easy disassembly, good sealing effect has improved the precision of test findings, and is time saving and energy saving and reduced cost.Solved the problem that the special-purpose pressue device of decompression dismounting was operated and the die trial cooling makes test block and die trial slide and seal with wax destruction and seep water relatively again after test block and die trial were sealed with wax preferably, loosened the test block under pressure water action of die trial top pressue device after test finishes simultaneously and also easily from die trial, take out.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a background impermeability test process flow diagram.
