The invention discloses a high-strength
cement-based self-leveling
mortar prepared by desulfurization
calcium plaster, and belongs to the technical field of self-leveling
mortar. The high-strength
cement-based self-leveling
mortar prepared by desulfurization
calcium plasteris prepared from the following raw materials in parts by weight: 18 to 28 parts of desulfurized
calcium plaster, 30 to 37 parts of
aluminate cement, 5 to 6 parts of
Portland cement, 35 to 39 parts of natural siliceous sand, 0.7 to 0.8 part of water
reducing agent, and 0.01 part of thickener. The invention further discloses apreparation method of thehigh-strength cement-based self-leveling mortar prepared by the desulfurization calcium plaster. According to the high-strength cement-based self-leveling mortar prepared bythe desulfurization calcium plaster and the preparation method thereof, the performance characteristics of the desulfurized calcium plaster, high-
alumina cement, and the ordinary
Portland cement are fully utilized respectively, the prepared cement-based self-leveling mortar has the characteristics that the setting and hardening speeds are fast, fracture resistance and crush resistanceof early andlater periods are high,
wear resistance is good,the surface is not prone to being pulverized, and
impact performance is good; the plasterin the desulfurized calcium plaster is not subjected to treating processes such as pressure
filtration and
drying, so that the dispersion effect of the desulfurized plasterin
cement slurry is better, the production cost is lowered, new approaches are provided forpreparation of cement-based self-leveling mortar and
resource utilization of desulfurizedcalcium plaster,and economic and environmental benefits are good.
