Abstract
The invention discloses a high performance cement-base self-leveling mortar. The mortar is characterized by comprising cement, an auxiliary gel material, fine aggregate, a filling material, an additive, and water; wherein the cement is common silicate cement and sulphoaluminate-silicate cement, the auxiliary gel material comprises mineral slag, fly ash, silica fume, and gypsum, and the ratio of common silicate cement to sulphoaluminate-silicate cement to gypsum is equal to 1:0.2-0.6:0.1-0.4. The mortar has a self-leveling function without vibration, so the surface flatness is very high. The curing speed of the mortar is very quick, and after two hours, the strength of the mortar can meet the requirements of subsequent construction. Moreover the mortar has the advantages of low contraction rate, good volume stability, good surface wear resistance, and high compression strength.
Description
technical field [0001] The invention relates to a cement-based building material, in particular to a high-performance cement-based self-leveling mortar. Background technique [0002] Cement-based self-leveling mortar is composed of cementitious materials, fine aggregates, fillers and admixtures, etc. It is a self-leveling material with high fluidity after adding water. It has good fluidity and self-leveling function, and can be quickly solidified. It can be constructed on the floor material in a short time. It is firmly bonded to the substrate and has good characteristics such as high compressive strength. In recent years, not only has it been widely used in self-leveling floors, but it has also been greatly developed as a final finishing material. However, cement-based self-leveling mortar still has technical defects such as shrinkage cracking, hollowing, poor wear resistance, poor surface smoothness, and slow strength development in engineering applications. It is urgent ...
