Fibercon is used to reinforce shotcrete in major projects around the world.
Fibercon in shotcrete provides ductility to a normally brittle material. Fibercon Steel Fibre Reinforced Shotcrete is attractive as it provides greater flexural strength, flexural toughness, improved durability and application efficiencies.
The homogeneous reinforcement of Fibercon gives resistance to tensile stresses at any point in the shotcrete layer. This also provides crack control from shrinkage and temperature gradients.
The use of Fibercon contributes to a lowering of project cost and improved productivity. Fibercon reinforced shotcrete offers a highly durable, timely and maintenance free support system that can be integrated into a ground support regime including rock bolts, cable bolts or steelsets
The toughness characteristics of Shotcrete are enhanced by the presence of a high tensile steel fibre throughout the concrete. The high tensile steel fibres bridge cracks thus enabling the concrete to support load after failure.
Long term durability is also enhanced as the fibres provide a matrix with a discontinuous reinforcement that can withstand a corrosive environment.
Fibercon Shotcrete can also be applied by remote robotic machinery at heights over 10 metres. This allows for a very safe work environment as personnel can secure areas while reducing exposure in difficult ground.
As a result, Fibercon reinforced shotcrete can be used in conditions that would otherwise require expensive traditional methods that could put personnel at risk.
- For flashcoats Fibercon shotcrete offers instant reinforcement.
- On rough uneven ground Fibercon shotcrete can follow the surface contours. This can mean a significant saving in materials and in labour.
- Fibercon has superior physical properties which can allow the use of thinner layers of shotcrete for the equivalent performance, this can provide significant cost savings.
- With no mesh to place onsite labour and time can be reduced.
- Safety is increased with use of robotic machinery.
- Fibercon increases the flexural toughness and is superior to mesh reinforced concrete.
- Thicker layers can be sprayed as fibres assist in providing greater buildup. Rebound will also be minimised.
- Punching strength is improved and this can enhance shotcrete used with bolting methods.
