Abstract

The invention relates to self-leveling mortar and in particular relates to thick self-leveling mortar. The mixture of the thick self-leveling mortar disclosed by the invention before use comprises the following components: 5-10 mass parts of sulfate aluminum cement, 20-25 mass parts of Portland cement, 5-10 mass parts of heavy calcium powder, 0.05-0.08 part of tartaric acid, 0.08-0.1 mass part of lithium carbonate, 0.2-0.3 mass part of a polycarboxylate superplasticizer, 0.05-0.08 mass part of cellulose with the viscosity of 400mPa*s and 0.1-0.15 mass part of a dry powder antifoaming agent. The thick self-leveling mortar disclosed by the invention can be rapidly dried to reach a usage state and is not cracked when the construction thickness is large.

Description

technical field [0001] The invention relates to a self-leveling mortar, in particular to a thick self-leveling mortar. Background technique [0002] Self-leveling mortar is a dry-mixed powder material composed of a variety of active ingredients, which can be used after mixing with water on site. After a little spreading with a scraper, a high flat base surface can be obtained. The hardening speed is fast, and you can walk on it within 24 hours, or carry out follow-up projects (such as laying wood floors, diamond boards, etc.), and the construction is fast and simple, which is unmatched by traditional manual leveling. [0003] Self-leveling mortar is safe to use, pollution-free, beautiful, fast construction and putting into use are the characteristics of self-leveling mortar. It can improve the construction procedure, create a high-quality, comfortable and flat space, and the paving of various Peugeot decorative materials adds brilliant colors to life. Self-leveling mortar...
