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 sk
