Shotcrete
Shotcrete is a method of applying concrete projected at high velocity primarily onto a vertical or overhead surface. The impact created by the application consolidates the concrete. Although the hardened properties of shotcrete are similar to those of conventional cast-in-place concrete, the nature of the placement process results in an excellent bond with most substrates and rapid or instant capabilities, particularly on complex forms or shapes.
Shotcrete Process
It 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, while 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).

Application Of Shotcrete
The application of shotcrete is highly versatile and can include the construction of new foundation walls, permanent and/or temporary shoring systems, and rehabilitation and repairs. The shotcrete market is a rapidly growing sector with increased demands due to the advantages in time and cost savings. Crews, pump operators, and nozzle operators must be experienced and certified to ensure quality. Annual and project-specific testing is often required to ensure competency and quality.
