Shotcrete, or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. 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.
It's mainly used for wet spraying for roads, railways, mining and tunnel, spraying mixed vegetation for slope of road and railway, grouting for wall, pumping fine aggregate concrete and so on. Features: ♦ Wet spraying machine has stepless speed change. The conveying output is 0-7 cubic meters / hour. ♦ The machine has hydraulic power.
