Wet-Mix Shotcrete Machine Advantages

Wet-mix shotcrete machine advantages:
1. Greatly reduces the dust concentration in the machine next to and outside of the nozzle, eliminating health hazards to workers.
2. High productivity. Dry concrete jet generally not more than 5m3 / h. The use of Wet-mix shotcrete machine, when manual work up to 10m3 / h; when using the robot operations, is up to 20m3 / h.
3. Low rebound degrees. When dry spray concrete rebound of up to 15% -50%. Wet spray technology. Spring rate can be reduced to 10% or less.
4. Wet spray, due to water-cement ratio is easy to control, not of a high degree of concrete, it can greatly improve the quality of shotcrete mouth, improving the concrete homogeneity, while dry spray, water-cement ratio of concrete by hand spray according to the experience and eye view of the investigation to be adjusted, the quality of the concrete depends largely on whether the right-hand operation machine.
