Shotcrete can combine the transportation, pouring and tamping of concrete into a single process, and can eliminate the formwork. It can also spray the arbitrarily from the obstacle through the hose to the long distance working face. The process is simple and flexible. Has a wide range of adaptability.
Shotcrete is made of high-speed injection, which is made by repeated continuous impact of cement and aggregate to make the concrete dense. It can adopt a smaller water ratio (usually 0.4~0.45 ) and has higher mechanical strength. Injection has high bonding strength between the solid material, concrete and rock, concrete, etc., may be combined tensile and shear stresses transferred surface. In the construction of shotcrete, a quick-setting agent can also be added to the mixture to make the cement settle in 10 minutes, so that the concrete can be immediately obtained after spraying.
There are two types of sprayed concrete construction: dry spray and wet spray. At present, dry spray is used in China.
Shotcrete is a kind of concrete which is formed by means of a jetting machine, which uses compressed air to mix a certain proportion of the mixture, which is conveyed by pipeline and is sprayed at high speed onto the rock surface or other surface to be hardened by the spray surface.
