Abstract

The invention relates to a mono-component system sulphoaluminate cement self-leveling mortar. The mono-component system sulphoaluminate cement self-leveling mortar is a unitary system gelling material self-leveling mortar only adopting sulphoaluminate cement as a gelling material. The formula of the self-leveling mortar comprises 31-50% of sulphoaluminate cement, 35-50% of fine sand, 5-25% of an inert filler, 1-5% of re-dispersible latex powder, 0.05-0.3% of a dispersant, 0.1-0.2% of an antifoaming agent, and 0.05-0.15% of a water retaining agent. The sulphoaluminate cement is adopted as the gelling material, so the sulphoaluminate cement can well solve the shrinkage problem of traditional self-leveling mortars after hardening. The self-leveling mortar has the advantages of low shrinkage, high flexural and compressive strength, simple and stable formula and protruding performances, and is cheaper than traditional multi-component system self-leveling mortars.

Description

Technical field [0001] The invention relates to a cement self-leveling mortar building material, in particular to a cement self-leveling mortar that can be directly used as a ground load leveling layer, and more specifically to a self-leveling mortar building material of a sulfoaluminate cement unitary system. Background technique [0002] Cement self-leveling mortar was developed in the 1970s. It is a product with high technological content and complex technical links. It is composed of a variety of cementitious materials, fine aggregates and various additives through dry mixing. For powdery materials, add water on site and stir to form a fluid substance that can flow homeopathically on the ground. It will automatically level on the ground and quickly solidify and dry to form a smooth, high-strength, and seamless new surface layer. Various floor materials such as carpets, PVC and rubber elastic floors, wooden floors, and floor tiles can be laid on its surface. At the same time, ...
