Quick-setting self-leveling mortar
The invention provides a quick-setting self-leveling mortar. The quick-setting self-leveling mortar is prepared from, by mass, 16-18% of 42.5-strength ordinary Portland cement, 7-10% of stone powder,42% of 0-1.2 mm machine-made sands, 5-15 % of 1.2-2.4 mm machine-made sands, 18-28% of 2.4-4.75 mm machine-made sands, 0.02-0.03 % of cellulose ether, 0.02% of a thixotropic lubricant and 0.1% of a water reducing agent. All the components are mixed; when the mortar is used, 14-16% of water is added, and uniform mixing is performed for instant use; components adopting the machine-made sands, gradation has good regulation performance, and the stability of the product can be ensured; the stone powder is ash powder sucked out by a dust collection system in the limestone crushing process, and the stone powder is used as an additive, so the stone powder is absorbed to prevent the ash powder from causing air pollution and improve the crushing environment, the resource utilization rate is increased, and the stone powder is prevented from being stacked at will; and the magnesium aluminum silicate thixotropic lubricant has high hydrophilicity, and the thixotropic lubricant forms non-Newtonian liquid type thixotropic gel in an aqueous solution, so that the self-leveling mortar is easy to flow.
本发明提供一种快速凝结自流平砂浆，由以下质量分数的成分组成：42.5强度普通硅酸盐水泥：16~18%；石粉：7~10%；0‑1.2mm的机制砂：42%；1.2‑2.4mm的机制砂：5~15%；2.4~4.75mm的机制砂：18%~28%；纤维素醚：0.02~0.03%；触变润滑剂0.02%；减水剂0.1%。本发明中的各成分经混合而成，使用时，加入14%~16%的水拌合均匀，即可使用，采用机制砂的成分，级配具有较好的可调控性，且可保证产品的稳定性，其中所述石粉为石灰石破碎过程中吸尘系统所吸出来的灰粉，以石粉作为添加剂，一方面吸取石粉防止灰粉造成空气污染，改善破碎环境，另一方面提高资源利用率，防止石粉任意堆放，硅酸镁铝触变润滑剂具有高度亲水性，触变润滑剂在水溶液中形成非牛顿液体类型的触变性凝胶，使自流平砂浆易于流动。
