HAREX steel wire fibre,
good at blending in fresh concrete, are ideal for shotcrete,
both wet process and dry process |
| |
Application fields:
·
Tunnel pre-treatment (initial support)
· Tunnel forming
(eternal lining)
· Slope stabilization
· Ditch wall
support
· Concrete restoration
|
|
|
|
Technical advantages:
· Better
workability retained
· concrete ductiliy greatly
increased
· Concrete tensile strength increased
· Fibres
uniformly and isotropically distributed
· Free from dead
angles during spraying
|
 |
 |
| Rebar mesh may cause dead angles
during spraying as rebars may partly hinder spraying, hence
shotcrete being uncompact. |
Economic benefits:
·
Rebar mesh cancelled
· Concrete consumption saved
·
Tunnel excavation saved
· Construction time
saved |
