High-cohesiveness cement-based grouting material for coal mine as well as preparation method and application of high-cohesiveness cement-based grouting material
The invention provides a high-cohesiveness cement-based grouting material for a coal mine as well as a preparation method and application of the high-cohesiveness cement-based grouting material, and belongs to the technical field of grouting materials. The grouting material provided by the invention comprises the following components in parts by mass: 900-1000 parts of superfine cement, 10-20 parts of a water reducing agent, 1-6 parts of a binder, 1-7 parts of talcum powder, 5-15 parts of a defoaming agent, 0-100 parts of fly ash and 700-900 parts of water. Compared with the existing cement grouting material, the cement grouting material disclosed by the invention has the advantages of high slurry stability, good fluidity, strong groutability and almost no bleeding phenomenon, and shows higher bonding and reinforcing strength, enhanced coordinated deformation capability and better durability in a full-length grouting system as a binder.
本发明提供一种用于煤矿的高粘结性水泥基注浆材料及其制备方法和应用，属于注浆材料技术领域。本发明的注浆材料包括900‑1000质量份的超细水泥、10‑20质量份的减水剂、1‑6质量份的粘结剂、1‑7质量份的滑石粉、5‑15质量份的消泡剂、0‑100质量份的粉煤灰及700‑900份质量份的水。本发明与现有水泥注浆材料相比，浆液稳定性高，流动性好，可注性强，几乎无泌水性现象，作为粘结剂在全长注浆体系中表现出更高的粘结加固强度、增强的协调变形能力和较好的耐久性。
