Slag-based road grouting material and preparation method thereof
The invention provides a slag-based road grouting material and a preparation method thereof. The slurry is stable, the precipitation and separation phenomena are avoided, and the compressive strengthof each age, the fluidity at different time and the expansion rate meet the standard requirements. The slag-based road grouting material comprises a cementing material and an additive, the cementing material comprises the following raw materials: 50-70 parts of slag powder, 6-10 parts of desulfurized gypsum, 5-9 parts of a special alkaline activator for slag, and 20-30 parts of fly ash, and the additive is prepared from the following raw materials in parts by weight: 0.3-0.4 parts of a hypophosphite modified polycarboxylate superplasticizer, 0.1-0.2 parts of a retarder, 0.5-0.6 parts of an expanding agent, and 0.04-0.06 parts of an antifoaming agent.
本发明提供了一种矿渣基公路压浆料及制备方法，浆体稳定，不会出现沉淀离析现象，各龄期抗压强度、不同时间流动度、膨胀率都满足标准要求。矿渣基公路压浆料，包括胶凝材料和外加剂；胶凝材料包含原料：矿渣粉：50‑70；脱硫石膏：6‑10；矿渣专用碱性激发剂：5‑9；粉煤灰：20‑30；外加剂包含以下重量份数原料：次磷酸盐改性聚羧酸减水剂：0.3‑0.4；缓凝剂：0.1‑0.2；膨胀剂：0.5‑0.6；消泡剂：0.04‑0.06。
