Steel fibres come in various shapes and qualities. Like with any other reinforcement, it is important to provide the required amount of fibres in a given section. However, it is not only the fibre dosage that governs the mechanical response of SFRC. Other factors that influence the mechanical response are:
- fibre length
typically from 30 mm to 60 mm - fibre diameter
typically from 0.3 mm to a maximum of 1.3 mm - fibre shape
straight, hooked, undulated, crimped, twisted, coned - fibre tensile strength
depends on material quality and ranges approximately from 800 MPa to 2500 MPa
