Cement-based grouting material for semi-flexible mixture and preparation method of cement-based grouting material
The invention belongs to the technical field of cement grouting materials, and particularly relates to a cement-based grouting material for a semi-flexible mixture and a preparation method of the cement-based grouting material. The cement-based grouting material is composed of the following components in parts by weight: 35-50 parts of sulphoaluminate cement, 10-20 parts of slag powder, 10-20 parts of fly ash, 6-7 parts of a chemical additive, 0.3-0.4 part of modified graphene fiber and water. The modified graphene fiber is prepared by adopting simple wet spinning and oxygen plasma etching technologies, has excellent flexibility, is well dispersed in an aqueous solution, and has high surface roughness and tensile strength. The obtained modified graphene fiber is incorporated into the sulphoaluminate cement-based grouting material, so that the mechanical property and the electrical property of the synthesized composite material are remarkably improved, and the dispersing property of the composite material in a cement system can be remarkably improved through a chemically modified water reducing agent.
本发明属于水泥灌浆材料技术领域，特别涉及一种半柔性混合料用水泥基灌浆材料及其制备方法，由以下重量份的组分组成：硫铝酸盐水泥35‑50份，10‑20份矿渣粉、10‑20份粉煤灰、6‑7份的化学添加剂、0.3‑0.4份改性石墨烯纤维、水；改性石墨烯纤维采用简易湿纺丝和氧等离子体蚀刻技术制备，具有优异的灵活性，在水溶液中分散良好，高表面粗糙度和抗拉强度。所得的改性石墨烯纤维被纳入硫铝酸盐水泥基灌浆材料中，使合成的复合材料的机械性能和电气性能有显著提高，通过通过化学改性的减水剂能够显著提高其在水泥体系中的分散性能。
