The usage amount of high-alumina cement in dry mortar is gradually increasing in Europe, America and other developed countries. It is mainly used to prepare special dry mortar with special performance and purpose to meet various high standards in construction. For example:

1. Various fast and rigid mortar for the purpose of shortening the construction period and quickly delivering the mortar for use, mainly taking advantage of the quick setting and fast hardening characteristics of high aluminum cement and Portland cement mixture;

2. For the purpose of obtaining excellent patching performance, various patching mortar mainly USES the fast hardening characteristics of high-alumina cement, silicate cement, gypsum and other mixtures and can react to form ettringite with expansion characteristics;

3. Non-shrinkage grouting material, which mainly USES high-alumina cement, silicate cement, gypsum and other mixtures to react to form ettringite with expansion characteristics, is used for foundation anchoring of large-scale equipment, installation of high-precision equipment and construction of steel structure buildings;

4. Waterproof and plugging materials, mainly using high aluminum cement, lime, gypsum;Or high aluminum cement, Portland cement, lime, gypsum and other materials of rapid reaction capacity and rapid formation of expansive ettringite performance;

5. There are more than ten raw materials for self-leveling floor materials, among which the reaction and control technology of high-alumina cement, silicate cement and gypsum is an indispensable part of self-leveling floor materials;

6. The wall and floor tiles are pasted with cement-based mortar. In order to adjust the setting and hardening time of mortar and reduce the shrinkage and other properties, it is also necessary to add high-alumina cement to solve the problem.
