The invention discloses ceramsite dual-doped shotcrete for high-temperature tunnel rock surfaces. The concrete comprises, by cubic meter, 485-500kg of cementing materials, 450-465kg of ceramsite and 0.9kg of polypropylene fibers, wherein the cementing materials include 65-75% of cement, 15-20% of coal ash and 10-15% of slag powder. Accelerator is added by 3-5% of the weight of the cementing materials in concrete preparation, and the ratio of the water to the cementing materials is not larger than 0.5. The shotcrete has the thermal conductivity lower than that of normal shotcrete by 65-70% under the synergistic effect of the materials of a certain proportion, and the modulus of elasticity of the shotcrete is 32-40% lower than that of normal shotcrete with similar compressive strength to the shotcrete. In addition, the polypropylene fibers of a certain quality are doped in the ceramsite concrete to form a three-dimensional network structure, lightweight aggregate is prevented from floating upward while strength and toughness are enhanced, viscosity of the ceramsite concrete is increased, layering segregation of the concrete is reduced, concrete materials can be distributed more uniformly, stability of the ceramsite concrete is further improved, and the ceramsite dual-doped shotcrete is especially suitable for construction of heat-damaged tunnels.
