Abstract

The invention discloses rapid ground leveling mortar. The rapid ground leveling mortar is prepared from the following raw materials in parts by weight: 200 to 350 parts of cementing material, 500 to 600 parts of aggregate, 100 to 200 parts of filler, 0.5 to 1.0 part of water reducing agent, 0.3 to 1.0 part of water retaining agent, 0 to 20 parts of latex powder, 0 to 1 part of retarder, 0 to 1 part of early strength agent and 0 to 1 part of anti-foaming agent. The rapid ground leveling mortar has a high levelling property and a high self-healing property, is free from sedimentation and bleeding, has high bonding strength with a base layer, is easy and convenient for ground construction, and can be used for realizing mechanical large-scale rapid construction; meanwhile, accurate ground leveling of 10 to 60mm in thickness can be realized, the single construction thickness is larger than 10mm, and fracturing and hollowing are avoided while the maximum single construction thickness is up to 60mm; people can tread on the ground 2 to 4 hours after construction, the strength can be up to the final strength of ordinary M15 ground mortar after 24 hours, a construction flow is realized, high construction efficiency and low labor strength are achieved, and the ground leveling construction period can be greatly shortened.

Description

technical field [0001] The invention relates to a leveling mortar, in particular to a quick ground leveling mortar. Background technique [0002] At present, the leveling materials for home decoration and large-scale public places are mostly made of ordinary ground leveling mortar or cement mortar mixed on site. At present, the disadvantages of these materials are: (1) The product quality is difficult to control, and the flatness is mainly determined by the level of the master worker; (2) The strength of ordinary ground leveling mortar and ready-mixed cement mortar is low the next day, and there is no early strength As a result, the moisture content of the base layer is high, and PVC materials cannot be paved; (3) the construction efficiency is low and the labor intensity is high; (4) the shrinkage rate of ordinary ground leveling mortar and ready-mixed cement mortar is relatively large, the later strength is low, and it is easy to Sanding occurs. Furthermore, the traditio...
