Influence of the Amount of Steel Fibers on Fracture Energy and Drying Shrinkage of HPFRCC

Table 2

Properties of steel fiber (SF).

Type	L/D	L (mm)	D (mm)	ft (MPa)	E (GPa)	ρ (g/m^3)
SF	65	13	0.2	2600	200	8.0

Note. SF: steel fiber; L/D: length to diameter ratio; L: length; D: diameter;f_t: tensile strength; E: elastic modulus; ρ: density.
