COMPARISONS BETWEEN CLOSED-LOOP AND STRAIGHT METAL FIBRES IN CONCRETE

Concretes containing closed-loop fibres and conventional straight fibres are compared for workability, bond strength, compressive strength, tensile strength, flexural strength and toughness. The concept of spacing is treated briefly. Tests indicate that all fibres have little effect until after significant cracking occurs. After cracking, closed loops offer much better integrity than straight fibres. Closed-loop fibres reduce the variability of both compressive and tensile strengths. (Author/TRRL)
