Shotcrete is applied using a wet or dry mix process
Shotcrete has been widely used in building repair, lining and reinforcement, slope and surface temporary support and other projects due to its advantages of convenient, fast construction and low overall cost，especially in places with thin sections and large areas, the use of shotcrete can effectively save construction time.
Shotcrete is applied using a wet or dry mix process, using a wet or dry shotcrete machine. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. Rebound is the shotcrete material that 'bounces' off the shooting surface. Wet-mix shotcrete rebounds somewhat less than dry-mix shotcrete.
Wet spraying is a new sprayed concrete technology developed for the problems of dry spraying, such as large dust, large rebound rate, and insufficient hydration. The obvious feature of wet shotcrete is that the concrete mixture is added with sufficient mixing water before entering the shotcrete machine or in the jetting machine, mixed evenly, and then sent to the nozzle through the feeding hose to be sprayed onto the sprayed surface. Therefore, the water-cement ratio of concrete can be accurately controlled, which is beneficial to the hydration of water and cement. Therefore, the dust is small, the rebound is less, the homogeneity of the concrete is good, and the strength is easy to ensure, but the water consumption is greater than that of dry spraying. Compared with dry shotcrete machine, it is more complicated and costly. Wet shotcrete machine is the main equipment for wet spraying.
