Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings. The protection scope of the present invention is not limited to the embodiments, and any changes made by those skilled in the art within the scope of the claims also belong to the protection scope of the present invention.

[0015] The test method for detecting the impermeability of mortar in the present invention is as follows: firstly, the silicone acetate sealant and the quick-hardening sulfate cement are evenly mixed according to the weight ratio of 2:1 to prepare the mixed sealant. When adding the hard sulfate cement material to the acetate silicone sealant, sprinkle it evenly on the colloid, add it in two times, wear environmentally friendly anti-acid gloves and perform repeated grasping operations to make the fast hard sulfate cement and silicone acetate sealant well mixed. Put the cured mortar block to be tested into the standard laboratory...

Abstract

The invention relates to a test method for detecting impermeability of mortar. The test method comprises the following steps: putting a cured mortar block to be tested into a standard laboratory for static drying for 0.5h, and uniformly coating the inner wall of an impermeability test mold with mixed sealant, wherein the thickness of the mixed sealant is 1 to 2mm; then, pressing the mortar block into the impermeability test mold with a press to form a mortar test block, extruding colloid from the upper and lower crevices of the mortar test block, and carrying out a coating operation again if crevices occur in the mortar test block; and keeping the bottom surface of the mortar test block into which the mortar block is pressed parallel to the bottom surface of the impermeability test mold, scraping the colloid extruded from the crevices above and below the mortar test block, and carrying out an impermeability test after 2 hours in the laboratory, wherein the mixed sealant is prepared bymixing acetic silicone sealant and fast hardening sulphoaluminate cement in a weight ratio of 2 to 1. Through adoption of the test method, the problem of easy leakage during detection of high pressureintensity is solved; the detection operation process is optimized; and the detection effect and accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of building material performance testing, and relates to a mortar detection technology, in particular to a test method for detecting mortar impermeability. Background technique [0002] The impermeability performance of waterproof mortar seriously affects its use effect, so it is particularly important to test the impermeability performance of waterproof mortar in order to meet the requirements of use. At present, the impermeability pressure of mortar with waterproof performance is generally above 1.5MPa. According to the GB 23440-2009 standard, the 7d impermeability pressure requirement for mortar specimens is ≥1.5MPa. When testing the impermeability pressure of mortar specimens, it is necessary to put the mortar The block is coated with a layer of rosin paraffin liquid or a paste with a weight ratio of butter to cement of 1:3 for sealing, and then put into an anti-seepage test mold for fastening. The rosi...
