Quick-setting self-healing cement-based capillary crystalline material for tunnel leakage stoppage, and preparation method thereof
The invention discloses a quick-setting self-healing cement-based capillary crystalline material for tunnel leakage stoppage. The quick-setting self-healing cement-based capillary crystalline material is prepared from, by weight, 35-50% of Portland cement; 25-35% of quartz sand; 2.5-7.5% of quick-setting and quick-hardening cement; 1-5% of talcum powder; 2.5-7.5% of heavy calcium carbonate; 3-5% of active master batch; and 10-15% of an alkaline penetrant. The sum of the percentages of the raw materials is 100%. The bonding force and the impermeability are improved.
本发明公开了一种用于隧道堵漏的快凝自愈型水泥基渗透结晶材料，由以下重量百分比含量的原料制备而成：硅酸盐水泥35％～50％；石英砂25％～35％；快凝快硬水泥2.5％～7.5％；滑石粉1％～5％；重质碳酸钙2.5％～7.5％；活性母料3％～5％；碱性渗透剂10％～15％；上述各原料的百分比含量之和为100％。其粘接力与抗渗性均有提高。
