Lightweight high-strength cement-based tunnel void disease repair material and preparation method thereof
The invention discloses a light high-strength cement-based tunnel void repair material and a preparation method thereof, and belongs to the technical field of tunnel engineering materials. The light high-strength cement-based tunnel void repair material provided by the invention is prepared from the following raw materials in parts by mass: 280-320 parts of water, 850-950 parts of a cementing material, 320-400 parts of superfine fly ash floating beads, 4-6 parts of a water reducing agent and 8-12 parts of a shrinkage reducing agent, the cementing material comprises cement and silica fume, and the silica fume accounts for 5-10 wt% of the cementing material. The repairing material obtained by the invention has the properties of light weight, high strength, low heat conductivity and low shrinkage rate, has good interface compatibility with the existing lining structure, and can effectively repair the tunnel structure cavity.
本发明公开了一种轻质高强水泥基隧道脱空病害修复材料及其制备方法，属于隧道工程材料技术领域。本发明提供的轻质高强水泥基隧道脱空病害修复材料由以下质量份数的原料制成：水280～320份、胶凝材料850～950份、超细粉煤灰漂珠320～400份、减水剂4～6份、减缩剂8～12份；所述胶凝材料包括水泥和硅灰，所述硅灰占胶凝材料的质量分数为5～10wt％。本发明得到的修复材料具有轻质高强、低导热、低收缩率的性能，同时与既有衬砌结构界面相容性好，可以有效对隧道结构空洞进行整治。
