Embodiment 1

[0011] In the 4# building of Mintai Longfengyuan District, Zhangdian, Zibo, the anti-cracking cement mortar of the present invention is used for plastering the interior walls, and the volume ratio of the ingredients is: perlite: cement: 801 glue = 8: 3: 1, mixed with 2 % NANOTHIX B1490 type water-repellent agent, the thickness of the plaster is 20mm, and it can survive once construction. Compared with ordinary plastering, ordinary plastering needs to be plastered in two layers, while plastering with this proportion of mortar only needs to be plastered once, saving A construction process was carried out, and no cracks were found after plastering.

Embodiment 2

[0013] Binzhou Wanxin Times New City District, adopts the anti-cracking cement mortar of the present invention, and its batching volume ratio is: perlite: cement: 801 glue = 8.5: 3.1: 1, and 1.5% SHP50 type water repellent is added in it , Plastering thickness of 15mm, the construction survived once, and no cracks were found on the wall after construction.

Embodiment 3

[0015] The anti-cracking cement mortar of the present invention has a batching volume ratio of perlite: cement: 801 glue = 7.6: 3.0: 1, and the quality is good after construction.

Abstract

The invention relates to a cracking-resistant cement mortar for building plastering, which belongs to building materials, which is prepared from perlite, cement and 801 glue with a volume ratio of (7.5-9):(2.8-3.3):1. The cement mortar solves the cracking, bubbling and poor bonding property problems of the prior plastering material; and has the advantages of high coagulation and setting speed, and good fire resistant, acid and alkali-resistant, thermal insulation and sound absorption properties.

Description

technical field [0001] The invention relates to an anti-crack cement mortar, which belongs to building materials and is used for building plastering. Background technique [0002] As a plastering material, the traditional cement mortar has some shortcomings such as cracks, hollowing, and poor bonding performance. Secondly, due to the slow setting and hardening speed, the long interval between the plastering process and the final decoration process restricts the construction progress. Contents of the invention [0003] The purpose of the present invention is to provide an anti-cracking cement mortar, which can solve the problems of cracks, hollowing and poor bonding performance of plastering materials, and has a fast setting and hardening speed, and has good fire prevention, acid and alkali resistance, heat preservation and heat insulation and sound-absorbing properties. [0004] Anti-cracking cement mortar of the present invention, its batching volume ratio is: [0005] ...
