Fiberreinforced Concrete Elements For Tunnel In Israel

Fiberreinforced Projected Concrete For Tunnel Application

Steel fiber reinforced concrete is stronger, more ductile and less permeable than traditional concrete. In tunnels excavated using modern automated TBM Tunneling Boring Machine excavators, the lining of voussoirs precast concrete can also be used as a final coating and is one of the fastest growing applications today.

Behavior Of Fiber Reinforced Concrete Under

Concrete lining of tunnel are sometimes exposed to fire temperature by traffic accidents. Such fire temperature may cause explosion of concrete, or collapse of tunnel structure 1. We must avoid at least the human disaster in case of fire accident in tunnel. Durable concrete to fire temperature are required for infrastructure such as road tunnels.

The Use Of Steel Fibre Reinforced Concrete

Steel fiber reinforced concrete is commonly used in tunnel construction, as it provides additional flexural strength, reduces shrinkage cracking and reduces permeability. Fiber reinforced concrete is a composite obtained by adding a single type steel or synthetic or a blend steel synthetic of fibers to the concrete mix.
