Super-early-strength grouting material
The invention relates to the technical field of grouting materials, in particular to a super-early-strength grouting material which comprises the following substances in parts by mass: 400-550 parts of quick-hardening sulphoaluminate cement, 40-55 parts of fly ash, 400-500 parts of quartz sand, 1-7 parts of a water reducing agent, 0.1-2.0 parts of an early strength agent, 0.1-2.0 parts of a retarder and 120-200 parts of water. The scheme can be used for filling and grouting for concrete cracks and lining cavities of different degrees of tunnels, can also be used for reinforcing and grouting or emergency repair projects of airports, railways, highways, bridges and the like, and projects such as rapid anchoring of foundation bolts, water interception and leakage stoppage and the like, and has the advantages of rapid solidification, high highest strength, short operable time, small fluidity, high compressive strength, high strength and the like. And the treatment requirement of the operation tunnel in the 2-h skylight period can be met, and the efficiency and quality of leakage grouting treatment of the operation tunnel are greatly improved.
本发明涉及注浆材料技术领域，具体涉及一种超早强注浆料，包括下述质量份的物质：快硬硫铝酸盐水泥400～550份、粉煤灰40～55份、石英砂400～500份、减水剂1～7份、早强剂0.1～2.0份、缓凝剂0.1～2.0份、水120～200份。本方案可针对隧道不同程度的混凝土开裂、衬砌空洞进行填实注浆，也可用于机场、铁路、公路、桥梁等的加固注浆或抢修工程及地脚螺栓快速锚固、截水堵漏等工程中，具有快速凝固性，最高强度高，可操作时间短、流动度小、抗压强度大，可满足运营隧道2h天窗期治理要求，大大提高运营隧道渗漏注浆治理的效率及质量。
