Quick-setting paste material, preparation method and application
The invention provides a quick-setting paste material preparation method, which comprises: 1, pouring coal gangue and coal gasification slag into a stirring device, adding water into the stirring device, and carrying out mixing stirring for 1-3 min at a rate of 100-200 r/min so as to obtain a mixed material A, and 2, sequentially adding cement, fly ash, magnesium slag, a water reducing agent and water into the mixed material A, and carrying out stirring for 1-3 min at a rate of 100-200 r/min so as to obtain the quick-setting paste material. Mixing and stirring at the speed of 100 to 200r/min for 3 to 5 minutes to obtain slurry B; 3, sodium bicarbonate and an accelerator are added into the slurry B, mixing and stirring are conducted for 3-5 min at the speed of 100-200 r/min, and the rapid-hardening paste material is obtained. The quick-setting paste material provided by the invention is a cementing material, and more solid waste materials are used in the preparation raw materials, so that the cost can be effectively reduced; the coal gasification slag particles contain a large amount of spherical particles which properly replace part of gangue, so that the workability of the material can be improved, the flowability of slurry can be improved, and the distribution uniformity of each component after the material is cured can be improved.
本发明提供了一种速凝膏体材料的制备方法，所述方法包括如下步骤：步骤1、将煤矸石和煤气化渣倒入搅拌设备中，向搅拌设备中加入水，在100～200r/min速率下混合搅拌1～3min，得到混合物料A步骤2、向混合物料A中依次加入水泥、粉煤灰、镁渣、减水剂和水，在100～200r/min速率下混合搅拌3～5min，得到料浆B；步骤3、向料浆B中加入碳酸氢钠和速凝剂，在100～200r/min速率下混合搅拌3～5min，即得速凝膏体材料。本发明提供的速凝膏体材料为胶凝材料，制备原料中使用了较多的固废材料，能够有效降低成本；煤气化渣颗粒中有大量的球状颗粒，适量取代部分矸石，可以改善材料的和易性，提升料浆的流动性，增大材料固化后各组分分布的均匀性。
