Self-repairing early-strength high-strength sleeve grouting material and preparation method thereof
The invention discloses a self-repairing early-strength and high-strength sleeve grouting material and a preparation method thereof, and relates to the technical field of sleeve grouting materials. Comprising the following components: cement, modified waste rubber powder, graphene, silica powder, hydroxypropyl methyl cellulose, quartz sand, a polycarboxylate superplasticizer, azodicarbonamide, an organic silicon defoaming agent, lithium salt, gluconate, disodium hydrogen phosphate dodecahydrate, reinforced fibers and water. Wherein the mixing mass ratio of the silica powder to the graphene is 1: 100; the gluconate is sodium gluconate; the lithium salt is the main performance indexes of the lithium sulfate sleeve grouting material, including fluidity, compressive strength and plastic expansion rate. Through cooperation of all the components, the fluidity of the grouting material can be effectively improved finally, the compressive strength of the grouting material can be improved, and the application field of the prepared grouting material is widened.
本发明公开了一种自修复早强高强套筒灌浆材料及其制备方法，涉及筒灌浆材料技术领域，包括以下成分制成：水泥、改性废胶粉、石墨烯、硅微粉、羟丙基甲基纤维素、石英砂、聚羧酸减水剂、偶氮二甲酰胺、有机硅消泡剂、锂盐、葡萄糖酸盐、十二水合磷酸氢二钠、增强纤维、水；其中，硅微粉与石墨烯混合质量比为1:100；所述葡萄糖酸盐为葡萄糖酸钠；所述锂盐为硫酸锂套筒灌浆料的主要性能指标包括流动度、抗压强度以及塑性膨胀率。本发明，通过各组分的配合，最终可实现有效改善灌浆料流动度，并且，能够提高其抗压强度，拓宽了制成的灌浆材料的应用领域。
