High-temperature-impact-resistant high-entropy grouting material as well as preparation method and application thereof

The invention discloses a high-temperature impact resistant high-entropy grouting material as well as a preparation method and application thereof. The high-temperature impact resistant high-entropy grouting material comprises the following components in parts by mass: 80-100 parts of superfine cement, 4-6 parts of steel fibers, 40-50 parts of high-entropy alloy powder, 80-100 parts of water, 0.1-0.3 part of a water reducing agent, 20-25 parts of a reinforcing agent, 0.08-0.2 part of a waterproof agent, 0.04-0.1 part of a retarder and 0.08-0.2 part of an air entraining agent, the components are sequentially stirred and mixed according to the mass parts, so that the high-temperature-impact-resistant high-entropy grouting material is prepared. Then, the high-temperature-impact-resistant high-entropy grouting material is injected into the surrounding rock crack to reinforce the surrounding rock; the grouting material disclosed by the invention still has better high-temperature resistance and impact resistance af
