Multifunctional two-component gypsum-based self-leveling mortar and mortar construction mode
The invention provides multifunctional two-component gypsum-based self-leveling mortar and a construction method thereof. The multifunctional two-component gypsum-based self-leveling mortar comprises a component A and a component B, the component A comprises the following components in percentage by weight: 40-95% of gypsum powder; 3-10% of cement; 0-50% of stone powder; 0.5 to 1.6 percent of fiber; 0.05-1% of a water reducing agent; 0.05 to 0.5 percent of a defoaming agent; 0.05 to 1% of cellulose ether; 0.1 to 0.2 percent of a retarder; the component B is aggregate with a single particle size; the mass ratio of the component A to the component B is (1-2): 2. According to the invention, gaps of aggregate with a single particle size are filled with the self-leveling material, the use amount of gypsum materials is reduced, different aggregate types are utilized to provide different functions for self-leveling, when high-strength aggregate is used, the strength of a self-leveling pouring body can be increased, and when lightweight aggregate is used, the self-leveling material has heat preservation and sound insulation functions. The formula is simple, the self-leveling size change is small, and the application scene is wide. And meanwhile, the construction process is simple, the material consumption is low, and the flatness is high.
本发明提供一种多功能双组份石膏基自流平砂浆以及该砂浆施工方式，包括A、B两个组份；A组份按重量组份计算包括：40‑95％石膏粉；3‑10％水泥；0‑50％的石粉；0.5‑1.6％纤维；0.05‑1％减水剂；0.05‑0.5％消泡剂；0.05‑1％纤维素醚；0.1‑0.2％缓凝剂；B组份为单一粒径骨料；A、B组份质量比为(1～2)：2。本发明利用单一粒径骨料的缝隙，将自流平填充于骨料缝隙中，降低石膏材料用量，同时利用不同骨料类型为自流平提供不同的功能，当使用高强度骨料时能增加自流平浇筑体强度，当使用轻质骨料时能使自流平具有保温隔音功能。该发明配方简单，自流平尺寸变化小，应用场景广。同时本发明施工工艺简单，材料耗用量低，平整度高。
