Higher volume per hose size. benefits This process has several advantages over conventional concrete for new construction and repair work. Some of the benefits are as follows: It makes the structure less porous, which increases the strength of the concrete bond. Reducing construction time and reducing construction costs. For channel lining protection, bridge safety, and debris flow stabilization. It is used to rebuild dilapidated marine structures such as walls, docks, seas, etc. Disadvantages This process is expensive compared to conventional concrete. There is a lot of concrete waste. Dust is a problem in technique. dry mix Pre-mixed dry ingredients are placed in delivery equipment. Compressed air delivers the material through a high-velocity hose to the nozzle, where water is added. Advantages of dry mix shotcrete: Increase bonding ability and bond strength The water content is easily controlled in the nozzle, with no time limit for placing the material Materials can be transported in bags versus bulk trucks &#8211; good for remote locations It is more compatible with small volume works and thin coatings Wet mixture All ingredients, including water, are thoroughly mixed and fed into the delivery equipment. Wet material is pumped to a nozzle where compressed air is added to provide high speed for placement. Advantages of using wet mix: The water content in the batch plant is more carefully controlled Additions can be added based on design requirements Suitable for higher volume productivity Although both wet and dry mix shotcrete have certain advantages, advances in materials and equipment technology have made the two processes nearly interchangeable.
