The invention discloses high-temperature anhydrite sand-free self-leveling mortar and a preparation method thereof, the high-temperature anhydrite sand-free self-leveling mortar comprises the following components in parts by mass: 50 parts of high-temperature anhydrite, 0.05 part of fiber, 8.5-14 parts of an admixture, 19-20 parts of water and 0.75-1 part of a gypsum plastic stabilizer, and the high-temperature anhydrous gypsum is mixed-phase anhydrous gypsum prepared by heating dihydrate phosphogypsum at a high temperature, calcining and dehydrating, and the admixture is set as a cementing material for concrete meeting national standard requirements. The admixture is one or a mixture of more of Portland cement, fly ash, silicon powder, ground steel slag powder and mineral powder, the Portland cement is P.O42.5 ordinary Portland cement, the fly ash is II-grade fly ash, the silicon content of the silicon powder is greater than or equal to 90%, the ground steel slag powder is steelmaking slag ground steel slag powder, and the mineral powder is 95-grade mineral powder. According to the high-temperature anhydrite sand-free self-leveling mortar and the preparation method thereof, the high-temperature anhydrite sand-free self-leveling mortar has relatively high water resistance and high strength.
本发明公开了一种高温无水石膏无砂自流平砂浆及制备方法，包括高温无水石膏、掺合料、水、纤维、石膏稳塑剂，其各组分质量分数为：高温无水石膏50、纤维0.05、掺合料8.5‑14、水19‑20、石膏稳塑剂0.75‑1，所述高温无水石膏设置为通过将二水磷石膏高温加热煅烧失水制备而得到的混合相无水石膏，所述掺合料设置为符合国家标准要求的混凝土用胶凝材料，掺合料设置为硅酸盐水泥、粉煤灰、硅粉、磨细钢渣粉、矿粉其中的一种或者多种的混合物，所述硅酸盐水泥为P.O42.5普通硅酸盐水泥，所述粉煤灰为Ⅱ级粉煤灰，所述硅粉含硅量≥90%，所述磨细钢渣粉为炼钢矿渣磨细钢渣粉，所述矿粉为95级矿粉。该高温无水石膏无砂自流平砂浆及制备方法，具有较高的耐水性，强度也高。
