Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. Shotcrete is used in new construction and repairs and is suitable for curved and thin elements (ACI 506R).

Jun 1, 2023 · The shotcrete process requires less formwork and can be more economical than conventionally placed concrete. Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle.

shotcrete mixture. Shotcrete has been used for structural concrete sections for decades. Although many engineers allowed shotcrete placement in their projects, there were no code provisions directly in ACI 318. In 2019, ACI 318 recognized the value of shotcrete in structural concrete for buildings and added shotcrete-specific code requirements ...
