Abstract:
The causes of rebound in dry-mix shotcrete can be related to both the mix proportions and shooting technique. An experimental program was carried out to test the variation of rebound based on several factors, including: shooting consistency, cement content, aggregate gradation, silica fume content, accelerator type and content, air flow, thickness of application, and position of shooting and inclination angle.
