Shotcrete is a method of forcing concrete through hoses with compressed air. This delivers the concrete at a very high velocity. It can be used to make load bearing or structural components or nonstructural building applications. It is rated, in some cases as high strength concrete and never as low as normal. The adhesion or structural value is derived in part by the impact from the high speed delivery of the substance, as well as the common characteristics of normal concrete mixed in a relatively dry fashion. Shotcrete is made of Portland cement, water, aggregate and admixtures. This is the normal composition of cement that is delivered in other fashions. They are also reinforced with deformed bars pre stressed steel and welded wire. These are common cement reinforcement equipment.

Initially, Shotcrete was delivered in a relatively dry mix. Currently it is offered in a dry and wet formulation. When the mixture is used wet, it is delivered through the hose with water that is mixed into the Portland cement and aggregate prior to the product being extruded through the hose. Additionally, more compressed air is added at the extrusion point to increase the velocity. In the dry method, Portland cement and damp aggregate are premixed before the hose, and water is added separately from a separate hose at the nozzle point as the concoctions are projected simultaneously onto the surface. This action adequately hydrates and mixes the product.

Shotcrete can produce several thicknesses in a single application. This means that it can meet most building requirements in one application. When the application is overhead, several layers will be used to obtain the required thickness. This is also true for some vertical applications. Each layer can be as thin as 1 or 2 inches. The finishing of the product can be done in several smooth and rough trowel techniques, as well as broom and natural finishes. After adhesion and finish work, Shotcrete usually cures in approximately 1 week, depending on the curing conditions.

Shotcrete has been used for approximately a century. It has been used to form building and residences. Its ability to be used vertically and overhead has made its uses expand over the years it has been applied. Although recent Shotcrete construction California, it has been used in other countries and other parts of the U. S. for years. It is especially effective on making the curved features of building and structures, as well as its ability to be applied in thin layers. Shotcrete has some non-conventional uses also. It is often used as fire proofing to structures, buildings and as retaining and retention barriers and walls. It is also widely used in public engineering applications and in swimming pools.
