Shotcrete Wikipedia

Shotcrete, gunite / ˈ ɡ ʌ n aɪ t / or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique, first used in 1914.: 7 It is typically reinforced by conventional steel rods, steel mesh, or fibers. Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions.

Shotcrete in tunnelling and mining tu-freiberg.de

Shotcrete is often used in tunneling and mining to seal freshly uncovered surfaces and for the support of cavities to the wet spraying machine. The wet mix will be transported to the spray nozzle using compressed air in the thin flow process (Fig. ). The dense-flow process is conducted with standard cement piston pumps. The material is hydraulically transported in a com-pact form to the
