Non-dispersible high-temperature-resistant cement-based consolidation material in underground water environment and preparation method thereof
The invention belongs to the technical field of grouting materials, and particularly relates to a non-dispersible high-temperature-resistant cement-based consolidation material in an underground water environment and a preparation method thereof. The non-dispersible high-temperature-resistant cement-based consolidation powder is prepared from the following raw materials in percentage by weight: 75%-95% of a cementing material, 0%-8% of a suspending agent, 1%-10% of an expanding agent, 0%-3% of a high-temperature-resistant agent, 1.0%-2.5% of a water-retaining agent, 0.3%-2.0% of a dispersing agent and 0.05%-2.0% of a retarder. The cementing material is prepared from cement, superfine slag powder, fly ash and silica fume in a weight ratio of (2-10): 2: 2: 1. After the cement-based consolidation material is mixed with water, slurry is good in self-fluidity, free of bleeding and layering and good in high temperature resistance, the volume of the slurry is not shrunk after the slurry is condensed, and the whole pores or rock gaps can be effectively filled in grouting plugging at a high water flow rate.
本发明属于灌浆材料技术领域，具体涉及一种井下水环境不分散耐高温水泥基固结材料及制备方法。所述其包括不分散耐高温水泥基固结粉和水，不分散耐高温水泥基固结粉包括以下原料及其重量百分比：胶凝材料75%‑95%、悬浮剂0%‑8%、膨胀剂1%‑10%制成、耐高温剂0%‑3%、保水剂1.0‑2.5%、分散剂0.3%‑2.0%、缓凝剂0.05%‑2.0%；所述胶凝材料为水泥、矿渣微粉、粉煤灰和硅灰按照2‑10：2：2：1的重量比组成。该水泥基固结材料与水拌合后浆体自身流动性好，不泌水不分层，耐高温性能好，浆体凝结后体积无收缩，在高水流速下灌浆封堵中可以有效填塞整个孔隙或岩石缝隙。
