Quick-setting early-strength composite cementing material as well as preparation and application thereof
The invention discloses a quick-setting early-strength composite cementing material and a preparation method and application thereof, and belongs to the field of building materials, the quick-setting early-strength composite cementing material comprises the following raw materials by weight: 500 parts of coal slime, 100-120 parts of cement, 10-12 parts of a quick-setting early-strength agent, 80-120 parts of water, and 4-8 parts of a polycarboxylate superplasticizer. The preparation method comprises the following steps: uniformly stirring the cement, the water and the polycarboxylate superplasticizer for the first time, adding the coal slime for secondary stirring, then adding the quick-setting early strength agent, and uniformly stirring for the third time to obtain the quick-setting early strength composite cementing material. Meanwhile, the invention discloses application of the quick-setting early-strength composite cementing material in coal slime in-situ curing. The product provided by the invention realizes rapid hardening and water sealing of the bottom plate coal slime, and realizes rapid hardening early strength-long-term alkali activation durability of the coal slime. Moreover, the preparation method provided by the invention is simple and convenient, and is beneficial to popularization and application.
本发明公开一种速凝早强复合胶结材料及其制备方法与应用，属于建筑材料领域，包括以下重量份数的原料：煤泥500份，水泥100‑120份，速凝早强剂10‑12份，水80‑120份，聚羧酸减水剂4‑8份。其制备方法包括以下步骤：将水泥、水和聚羧酸减水剂一次搅拌均匀后，加入煤泥进行二次搅拌，然后加入速凝早强剂经三次搅拌均匀，得到所述速凝早强复合胶结材料。同时本发明公开了上述速凝早强复合胶结材料在煤泥原位固化中的应用。本发明提供的产品实现底板煤泥快速硬化与封水，实现煤泥速凝早强‑长期碱激发可耐久性。并且，本发明提供的制备方法简单方便，利于推广使用。
