Embodiment Construction

[0034] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it according to the text of the description.

[0035] The invention provides a method for quickly sealing an impermeability test piece of mortar, which comprises the following steps:

[0036] Step 1. After disassembling the mortar impermeability test piece, place it in a standard curing room to cure to the specified age, take out the mortar impermeability test piece, wipe it clean and dry the surface of the mortar test piece:

[0037] Step 2: Wrap the elastic film tape on the bottom and top of the mortar impermeable test piece to form a graded seal. The distance between the elastic film tape at the bottom of the mortar impermeable test piece and the bottom surface of the mortar impervious test piece is 10mm, the distance between the elastic film strip located on the top of the side wall of the mortar impermeable test piece and the to...

Abstract

The invention discloses a method for quickly sealing a mortar impermeability test piece. The method comprises the following steps: 1, taking a cured mortar impermeability test piece, wiping cleanly and airing; 2, respectively winding an elastic film belt at the bottom and the top of the side wall of the mortar impermeability test piece to form graded sealing, wherein the distance between the elastic film belt located at the bottom of the side wall of the mortar anti-permeability test piece and the bottom surface of the mortar anti-permeability test piece is 10 mm, and the distance between theelastic film belt located at the top of the side wall of the mortar anti-permeability test piece and the top surface of the mortar anti-permeability test piece is 10 mm; and 3, pressing the mortar anti-permeability test piece into an anti-permeability test mold so that the elastic film belt blocks a water flow rising path between the sealing test piece and the side wall of the anti-permeability test mold. The elastic film is used for sealing the mortar impermeability test piece so that the problem that the sealing coating is difficult to coat uniformly in the prior art is solved.

Description

Technical field [0001] The invention relates to the field of mortar performance detection. More specifically, the present invention relates to a method for quickly sealing mortar impermeability test pieces. Background technique [0002] The impermeability of mortar is an important index to evaluate the durability of mortar, which is obtained through the water-impermeability test of mortar, which is measured in accordance with "Test Method for Basic Performance of Building Mortar" JGJ / T 70-2009. [0003] The mortar impermeability test method specified in JGJ / T 70-2009 is to install a set of tested mortar impermeability test pieces into the test piece set and install them on a special mortar impermeability tester for testing. The test is performed on the bottom surface of the test piece. Pressurize with water according to the prescribed method, and obtain the impermeability grade of the tested mortar impermeability test piece through the observed surface leakage and internal penetra...
