Study on Tensile Damage Constitutive Model for Multiscale Polypropylene Fiber Concrete

Table 2

The amount of polypropylene fiber (kg/m³) for different specimens.

Specimen number	Fiber table	Mix amount (kg/m^3)
A0	None	0
A1	FF1	0.9
A2	FF2	0.9
A3	CF1	6.0
A4	(CF1 + FF1)^▲	6.0
A5	(CF1 + FF2)^▲	6.0
A6	(CF1 + FF1 + FF2)^•	6.0

Note: ▲ represents amount CF1 that is 5.1 kg/m³ and amount of FF1 or FF2 that is 0.9 kg/m³; • denotes the added amount of CF1 that is 5.1 kg/m³ and amount of FF1 or FF2 that is 0.45 kg/m³.
