Fiber is designed for reinforcement of highly loaded industrial floors, foundation slabs, piles, construction of precast concrete. Also used in road and airfield construction.
Steel fiber is made of low-carbon wire
The diameter of fibers: 1,00 mm ± 0,03mm
Length of fiber: 54mm ± 4mm
Head diameter: ≥ 1,8 mm
Angle of the cone: 700
Steel wire Fiber for concrete reinforcement
TU U 28.7-05393145-004:2005
as a disperse material with reinforcing steelfiberconcrete and torkretconcrete. Quality parameters of a fiber correspond to requirements of ASTM A 820 (to a fiber of type I)
FIBER is produced :
- by design features : Deformed with bent ends (DZ).
- By surface type: Without coating
- by mechanical properties:
1st group - with tensile strength 350-900 Н/mm2;
2nd group - with tensile strength more than 900 Н/mm2.
