Rapid repair material for high-speed rail tunnel diseases and preparation method of rapid repair material
The invention discloses a high-speed rail tunnel disease rapid repair material which comprises the following components in parts by mass: 200-250 parts of cement, 100-150 parts of superfine fly ash floating beads, 40-50 parts of an anti-cracking agent, 40-50 parts of an interface repair agent, 40-50 parts of a rheology modified material, 850-900 parts of coarse aggregate, 850-900 parts of fine aggregate and 4-5 parts of a water reducing agent, the anti-cracking agent is prepared from the following components in parts by mass: 40 to 50 parts of MgO, 40 to 60 parts of CaO, 10 to 15 parts of Al2O3 and 1 to 5 parts of quartz powder. Under the action of the anti-cracking agent, the interface repairing agent, the superfine fly ash floating beads and the rheological modification material, the characteristics of high early strength, short curing time and strong interface bonding can be realized, and the downtime is reduced, so that economic benefits are provided for tunnel maintenance and repairing.
本发明公开了一种高铁隧道病害快速修复材料，按质量份计，包括以下组分：水泥200‑250份，超细粉煤灰漂珠100‑150份，抗裂剂40‑50份，界面修复剂40‑50份，流变改性材料40‑50份，粗骨料850‑900份，细骨料850‑900份，减水剂4‑5份；所述抗裂剂，按质量份计，包括以下组分：MgO 40‑50份，CaO 40‑60份，Al2O310‑15份，石英粉1‑5份。通过抗裂剂、界面修复剂、超细粉煤灰漂珠和流变改性材料的作用，可以实现早期强度高、固化时间短、界面粘结强的特点，减少停工时间，从而为隧道维护和修复提供了经济效益。
