Special high-strength rapid repairing material for airport runway

The invention discloses a special high-strength rapid repairing material for an airfield runway. The special high-strength rapid repairing material comprises the following components in parts by weight: 350-500 parts of sulphoaluminate cement, 400-500 parts of sand, 20-100 parts of silica fume, 2-3 parts of a water reducing agent, 0.1-1 part of a coagulant, 1-5 parts of a retarder and 80-140 parts of water, and the water-binder ratio is 0.20-0.26. The special cement sulphoaluminate cement and the silica fume are combined, it is guaranteed that the later strength does not shrink on the basis that rapid hardening and early strength are met, the obtained high-strength rapid repairing material meets the 15-20-minute construction performance, and meanwhile the high-strength rapid repairing material has the advantages of being high in setting rate and high in early strength; the cement concrete pavement superficial layer repairing material meets the performance index requirements on the cement concrete pavement sup
