An overview of sprayed concrete or shotcrete

As a building material, many people are familiar with concrete. However, not everyone is familiar with the known form of shotcrete concrete. Here's some basic information on the shotcrete, the way it is used in construction projects today.

In essence, it is expected shotcrete concrete. Originally in the early 20th century was developed to fill shotcrete as a medium is, with the concrete forms created. The concrete itself was a dry mixture, which was blown directly into the formwith compressed air.

Since the concrete has been published, was moistened the mixture to dry so that he stop and get in shape. The inventor of this method, Carl Akeley received a patent in 1911 for the weapon is real, which has developed, as the material that was produced, who called Gunite.

Other applications of shotcrete are immediately apparent. Since the shotcrete may be convened before any horizontal or vertical shot of cement could be applied easily be applied to the sidesbuildings, the shotcrete could be used as a patch and as a filler that may have cracks in walls or foundations appeared. The fast-track the construction of sidewalks in front yards and gardens and patio, as they may shotcrete in a fraction of the time, mix the concrete application and placed by hand.

The dry method of production of shotcrete were continued in force until the mid-20th century, and further refinement. Still in use today, the dry methodcomes to the dry mixture into a hopper, where it ran on a tube with a water-attached at the end of the tube. Since the concrete is shot out the tube and the mechanism of gun, the operator adjusts the amount of water that is added to the dry mixture. The result is a mixture of concrete that is easy to drive, dry and cure at the same time that each method using cement.

Until the mid-20th century, an alternative method for the creation of shotcrete was developed.When the wet method is defined in this process with the ready-mixed concrete. As with the dry air process is used for the concrete mixture through a tube and a nozzle effect. In wet mixing, the operator has the capability of the mixture of water and dry concrete, as this process has already taken place. Fans of this method indicates that there is no possibility of introducing too much water in the mixture, a texture Bad concrete. Proponents ofOriginal method is that dry concrete reality and the water is a finished product that is more than ready-mix with wet.

Both applications are layers of steel bars or wire mesh is often used to help maintain the surface and the shotcrete receive treatment, is enhanced. With little more for the shotcrete to cling to itself, while it dries in place, the patches of shotcrete or causes tend to be much longer.
