Fluorine gypsum self-leveling mortar and preparation method thereof
The invention discloses fluorgypsum self-leveling mortar and a preparation method thereof. The fluorgypsum self-leveling mortar is prepared by uniformly mixing fluorgypsum, semi-hydrated gypsum, ordinary Portland cement, ash calcium, potassium sulfate, a defoaming agent, a water reducing agent, a retarder and cellulose. The industrial byproduct fluorgypsum is hydrated to generate dihydrate gypsum, and the dihydrate gypsum and Portland cement generate ettringite, so that the strength of the fluorgypsum self-leveling mortar is improved; portland cement is introduced and the proportion of the Portland cement is adjusted, so that the coagulation of the material is promoted, high-strength ettringite is generated with fluorgypsum, and the flowability of the material is improved. Therefore, the invention provides the gypsum self-leveling mortar with good physical properties, mechanical strength, water resistance and constructability and the preparation method thereof.
本申请公开了一种氟石膏自流平砂浆及其制备方法，包括：氟石膏、半水石膏、普通硅酸盐水泥、灰钙、硫酸钾、消泡剂、减水剂、缓凝剂、纤维素混合均匀制备而成。本申请通过将工业副产氟石膏水化生成二水石膏，二水石膏与硅酸盐水泥生成钙矾石，提高氟石膏自流平砂浆的强度；通过引入硅酸盐水泥并调节其配比从而达到促进材料的凝结，与氟石膏生成高强度的钙矾石，改善材料的流动性。从而提供了一种具有良好的物理性能、力学强度、耐水性较好，以及具有良好的施工性的石膏自流平砂浆以及制备方法。
