Spletrange and rebound rate was recorded, as shown in Table 3. Figure 3 shows the curve of the injection range and the rebound rate of the experiment. It can be seen from Figure 3 that when the particle size is 15mm, the spray distance is 1.0m, and the shrinkage angle is 8°. e rebound rate is low, and the spray range is small. Spletshall have a rich, glossy appearance and that the shotcrete shall adhere to the supporting surface without flowing, slumping, or sloughing.
