文摘
- •
This paper deals with Hybrid Steel/Polypropylene Fiber-Reinforced Concrete (HyFRC).
- •
It focuses on five HyFRC mixtures made with an invariant volume fraction of fibers.
- •
Experimental results from tests under both compression and bending are reported.
- •
Steel fibers mainly contribute to strain re-hardening force-crack response.
- •
Specimens with more polypropylene fibers exhibited a less variable response.
