Shotcrete is a material used in the construction industry. It is a mixture of concrete and aggregates that is sprayed onto surfaces. Shotcrete can be applied to any surface, but it is most commonly used to construct walls and floors.
Shotcrete can be applied to any surface, but it is most commonly used to construct walls and floors. Shotcrete can also be sprayed onto existing structures or surfaces, such as bridges and dams, to repair cracks or prevent further deterioration.
Shotcrete is a type of concrete sprayed onto a surface. It can be applied to a variety of surfaces, including steel, wood, plasterboard and glass. Shotcrete can be used for both interior and exterior applications.
It offers many benefits, including the ability to create strong, long-lasting structures quickly and with minimal labor costs, and also protects against fire and water damage.
What is shotcrete?
Shotcrete is a type of concrete that is sprayed onto surfaces by machine. It is often used for construction purposes, but can also be used for other purposes.
Essentially there are two types. Namely
- Dry shotcrete
- Wet shotcrete
Dry shotcrete is cheaper and easier to process than wet shotcrete. Wet shotcrete offers additional advantages over dry shotcrete in that it can also be easily processed in more difficult areas such as corners and around obstacles.
Spraying on surfaces is done with a high pressure water nozzle. The nozzle sprays concrete at about 40 to 90 pounds per square inch and can produce a thickness of between 4 and 8 millimeters.
This type of concrete is often used for construction purposes because it is more durable than regular concrete and can create a smooth surface.
Shotcrete as a construction method
Shotcrete is typically used to create structurally sound and weatherproof panels. It can be used as an alternative to other construction methods such as brick and mortar, precast concrete panels and plywood cladding. Shotcrete can also be used as temporary formwork for concreting other types of concrete structures such as bridges or. tunnel .
Due to its quick processing, low cost per square foot, and weather resistance, shotcrete is often preferred over these methods.
Shotcrete can be applied in different ways.
- sprayed from a nozzle
- pumped through pipes
- Apply manually with a spatula or roller
Advantages of shotcrete
Shotcrete is a type of concrete sprayed onto surfaces to make them resistant to fire, chemicals, and other hazards.
Shotcrete has many advantages over other types of concrete such as
- Reduced labor costs
- Possibility of application at any time of the day
- Can be applied quickly
- No skilled workers are required for installation
- In situ concrete that is mixed and poured on site
- It can be applied in different ways, such as: B. pouring from a bucket, hose or pipe.
- Reduced labor costs
- Can be processed as fine concrete
- Thin-bed concrete is a type of concrete that is mixed, installed and finished in a single operation.
- Can be easily repaired if damaged during installation
Application of shotcrete
It is normally used in
- Tunnel construction
- Mining
- Civil engineering work in areas where transporting concrete or placing formwork is difficult.
Shotcrete has been used in tunneling and mining projects for many years.
It is an alternative to other forms of tunnel lining, such as prefabricated panels and cast-in-place concrete linings.
It is also used as an alternative to traditional concrete in house construction because it does not require skilled labor for installation, can be processed quickly and the cost per unit area is relatively low.
In addition, shotcrete is used in subsequent works.
- Repair work on bridges, buildings, marine structures, spillway structures, etc.
- Underground excavation protection
- Protection of slopes and surfaces, such as nailing into the ground
- Swimming pools and tanks construction
- Dome construction
