The Wet And Dry Shotcrete Machine
Dry-mix shotcrete machine, is a name used to designate a mixture of 1 part Cement and 4 parts sand thoroughly mixed dry, passed through a gunite machine, and conveyed by air through a rubber gunite hose and deposited by air pressure. The large amount of air pressure serves to mix and compact the mixture. The result is a smooth, hard surface. There are two basic types of Shotcrete: Dry-mix shotcrete machine and Wet-mix shotcrete. Because the wet-mix shotcrete process generally results in less rebound, less waste has to be handled and disposed of. There is also less dust – an advantage when concrete must be shot in a confined area. Although placing techniques for both the wet and dry-mix shotcrete processes are similar, it much easier to control the nozzle; instead of wrestling a jerking hose he can concentrate on shooting the right amount of material at the right spot. Because forms are not required, shotcreting is a cost-effective method for repairing vertical and overhead surfaces. Advances in equipment and materials have made wet-mix gunite a practical repair option. Shotcrete has repeatedly demonstrated a versatility that few construction materials can rival. For most bridges, the original concrete will require additional repairs long before the shotcrete needs repair. Properly designed, applied, and cured, our shotcrete machine repairs suffered little deterioration.
