Ternary system cement-based self-leveling mortar
The invention discloses ternary system cement-based self-leveling mortar. The ternary system cement-based self-leveling mortar is prepared from high-alumina cement, ordinary portland cement, alpha-hemihydrate gypsum, coarse whiting, river sand, a water reducing agent, polysaccharide modified nano silicate, a retarder, a defoaming agent, a coagulation accelerator and rubber powder. According to theinvention, the polysaccharide modified nano silicate is added into the ternary system cement-based self-leveling mortar made of the high-alumina cement cementing material, so that the surface smoothness and rheological property of the self-leveling mortar are effectively improved, and the self-leveling mortar has excellent self-healing property and flatness.
本发明公开了一种三元体系水泥基自流平砂浆。该三元体系水泥基自流平砂浆包括：高铝水泥、普硅水泥、α‑半水石膏、重钙、河砂、减水剂、多聚糖改性纳米硅酸盐、缓凝剂、消泡剂、促凝剂、胶粉。本发明通过在以高铝水泥胶凝材料的三元体系水泥基自流平砂浆中加入多聚糖改性纳米硅酸盐，有效改善自流平的表面光滑程度以及流变性能，使自流平获得优良的自愈性和平整度。
