文摘
- •
Reinforcing effects of polyolefin fibres in concrete was studied through RDPT.
- •
Effects of fibre length, dosage and concrete strength on concrete toughness were studied.
- •
A new characterisation method using toughness index based on RDPT was presented.
- •
A combined synergetic effect of fibre length, dosage and concrete strength was found.
- •
Equivalent reinforcement was achieved by adjusting combinations of fibre dosage, length and concrete strength.
