Gypsum-based self-leveling mortar as well as application and construction method thereof
The invention discloses gypsum-based self-leveling mortar and application and a construction method thereof. The gypsum-based self-leveling mortar comprises the following components in percentage by weight: 20-40% of alpha-semi-hydrated gypsum powder fired by desulfurized gypsum; 5-20% of alpha-semi-hydrated gypsum powder fired from natural gypsum; 5-10% of coarse whiting powder; 5-15% of ash cement; 30-50% of sand; 0.5-2% of rubber powder; and 0.1-2% of a composite additive. Semi-hydrated gypsum (CaSO4.1/2H2O) and II-type anhydrous gypsum (II-type CaSO4) are used as a main cementing materialindependently or a mixture of the semi-hydrated gypsum (CaSO4. 1/2H2O) and the II-type anhydrous gypsum (II-type CaSO4) is used as the main cementing material, and/or the gypsum-based indoor floor self-leveling material with certain fluidity in a newly-mixed state is composed of aggregates, fillers and additives. The energy-saving effect is better; and the floor hardened by the gypsum-based self-leveling mortar has certain elasticity, and feet feel warm and comfortable.
本发明公开了一种石膏基自流平砂浆及其应用、施工方法。所述的石膏基自流平砂浆，包括以下重量百分比的组分：脱硫石膏烧制的α‑半水石膏粉20‑40％；天然石膏烧制的α‑半水石膏粉5‑20％；重钙粉5‑10％；灰水泥5‑15％；砂30‑50％；胶粉0.5‑2％；复合添加剂0.1‑2％。本发明以半水石膏(CaSO4·1/2H2O)和Ⅱ型无水石膏(Ⅱ型CaSO4)单独或两者混合后作为主要胶凝材料，和/或骨料、填料及外加剂所组成的在新拌状态下具有一定流动性的石膏基室内地面用自流平材料；节能效果更好；且石膏基自流平砂浆硬化后的地板具有一定弹性，脚感温暖舒适。
