Shotcrete is an all-inclusive term for spraying concrete or mortar with either a dry or wet mix process. However, shotcrete may also sometimes be used to distinguish wet-mix from the dry-mix method. The term shotcrete was first defined by the American Railway Engineers Association (AREA) in the early 1930s. [6]
Recently Conco has taken a role in the developing field of sculpted shotcrete, which is the use of concrete as a canvas to create shotcrete walls that have structural integrity but are aesthetically pleasing. Shotcrete provides an excellent alternative to traditional cast-in-place walls, and since it is pneumatically placed, greatly reduces ...
The primary advantages of fibre-reinforced shotcrete are: Addition of steel fibers into the concrete improves the crack resistance (or ductility) capacity of the concrete. Traditional rebars are generally used to improve the tensile strength of the concrete in a particular direction, whereas steel fibers are useful for multidirectional ...
Shoring is commonly used when installing the foundation of a building. A shoring system such as piles and lagging or shotcrete will support the surrounding loads until the underground levels of the building are constructed. Commonly used shoring equipment includes post shores, shoring beams, and timber jacks.
Incremental excavation with a shotcrete circular or elliptical lining; Incremental excavation supported by shotcrete, rock bolts, cable anchors and steel sets or ribs; Shafts can be sunk either dry or for methods such as the caisson method they can be sunk wet.
Shotcrete reinforcement and ground support is utilized at the tunnel portals and in the interior of the wine caves. At the portals, soil nail and shotcrete walls are typically used for permanent support and are constructed from the top down in lifts. Soil nails are installed 4 to 6 ft (1.2 to 1.8 m) apart in the horizontal and vertical directions.
