文摘
- •
The parameters that describe polyolefin fibres pull-out behaviour are reported.
- •
The critical length of polyolefin fibres was close to 20 mm in a concrete matrix.
- •
The results obtained can be used as benchmark for modelling or design assumptions.
- •
Micrographies showed sound interface between polyolefin fibres and cement paste.
- •
Pull-out work and load of polyolefin fibres were similar to those of steel fibres.
