ABOUT SHOTCRETE
WHAT IS SHOTCRETE?
The shotcrete (gunite) is defined as the mechanized application of concretes and compositions with a cement and non-cement binder (e.g., refractories, linings) without formwork. Shotcrete is a gunned layer of concrete, which obtained as a result of shotcreting. The difference between shotcrete and plastering, which is also often produced by a mechanical method.

The process of shotcrete is known for more than a hundred years, and the areas and scope of its use in the world are continuously increasing. Initially, dry shotcrete was used to reinforce soils and repair reinforced concrete structures. Subsequently, with the expansion of the capabilities of shotcrete equipment, shotcrete has become a more flexible technology capable of solving the most ...

DRY-MIX SHOTCRETE MACHINE АС-1
DESCRIPTION OF THE MACHINE
The AC-1 series machines for dry shotcrete are designed for applying concrete and refractory concrete by the so-called dry shotcrete method. This machine operates using a pocket-type one-sided dosing drum. The machine is produced in two types of execution—with an electric engine and a pneumatic engine, with a productivity of 0.4–3.2 m3/h. Versatility in use allows adapting the AC-1 to the most types of shotcrete works.
FIELD OF APPLICATION
The AC-1 series shotcrete machines are used for repairing concrete, ground reinforcement in underground and overland development, strengthening engineering structures, in the construction of hydraulic structures and tanks, reinforcing arches tunnels and collectors, carrying out the readjustment of concrete structures. Another important field of application is a refractory materials spraying. Compactness and mobility make the AC-1 the ideal machine for repairing concrete structures and underground development.
ADVANTAGES OF THE АС-1 SHOTCRETE MACHINE
- ease of movement and transportation due to the low weight of the machine; 1 worker can easily move the AC-1
- smooth output adjustment (VARIO version)
- long-term operation life due to reliable European components
- ability to work in the “start-stop” mode
- a simple cleaning of the apparatus and a rare choking of hoses
- possible to transport mixtures to long distances and to hard-to-get-at places
- low operating costs and long-term operation life of wearing parts
In response to the need to improve mobility and reduce materials consumption of the shotcrete equipment of classical design, the AC-1 machines have been developed. Thanks to the use of only one compaction plate, the machines in this series have a 30% reduced wear compared to machines with through-type rotor. The simplified and lightweight design makes the AC-1 an effective solution in the repairing of concrete, roadway supports, and the application of refractories.
The AC-1 is the “Kalashnikov automatic rifle” in the shotcrete.
DRY-MIX SHOTCRETE MACHINE АС-2
DESCRIPTION OF THE MACHINE
The AC-2 pneumatic concrete spraying machine is designed for shotcreting and refractory concrete by the so-called dry method. This machine is based on the classical rotary principle of action with through-type dosing rotor. The machine is manufactured in two versions—with a output of 0.5-4 m3/h. Changing the drum allows to additionally change the performance. The dual air supply system perfectly copes with dense and heavy mixes. In order to apply the refractory and lining layers, machines of this type are used in metallurgy, chemical, glass, cement industries, as well as in other enterprises that use furnaces.
FIELD OF APPLICATION
The AC-2 shotcrete machine can be used for the applying refractory shotcrete mixes and lining materials, repairing concrete, ground reinforcement in underground and overland development, strengthening engineering structures, reinforcing arches tunnels and collectors, carrying out the readjustment of concrete structures, and applying waterproofing mixes. Equipment of this type can be used for the transport of bulk solids and sandblasting.
ADVANTAGES OF THE MACHINE
- works well with big aggregate mixes (for example, refractory shotcrete mixes)
- a massive design that allows to work under severe conditions
- long-term operation life of wearing parts due to central lubrication
- smooth output adjustment (VARIO version)
- a simple cleaning of the apparatus and a rare choking of hoses
- possible to transport mixtures to long distances and to hard-to-get-at places
- low operating costs and long-term operation life of wearing parts
The classic design of shotcrete machines with through-type dosing drum has proven itself over many years of operation as extremely reliable, resistant to severe environment.
АС-3 DRY AND WET SHOTCRETE MACHINE
DESCRIPTION OF THE MACHINE
The АС-3 shotcrete machine is designed for shotcreting and applying of refractory concretes in a dry or wet method. This unit operates using a through-type dosing drum. The concrete sprayer machine is produced in two versions – with a output of 2–7 m3/h and 2–6 m3/h. Due to the special design of the charging hopper and the dispensing rotor, the sprayer can also be used for wet shotcrete. The АС-3 shotcrete machine is productive and the most versatile in the range of the АС shotcrete machines, and it can be adapted to any kind of gunite work.
FIELD OF APPLICATION
The AC-3 shotcrete machine can be used for the construction of buildings and structures without formwork, including using 3D panels, building swimming pools, applying refractory shotcrete mixes, repairing concrete, ground reinforcement in underground and overland development, strengthening engineering structures, reinforcing arches tunnels and collectors, carrying out the readjustment of concrete structures, and applying waterproofing mixes. Equipment of this type can be used for the transport of bulk solids and sandblasting.
ADVANTAGES OF THE MACHINE
- versatility with use of dry and wet mixes
- possible to feed liquid additives in the nozzle, applying large layers in one pass
- works well with big aggregate mixes
- a massive design that allows to work under severe conditions
- long-term operation life of wearing parts due to central lubrication
