What specific concrete properties does steel fibre technology improve?
• Flexural Strength – significant increase (1.5 to 3.0 times) in the first-crack and ultimate flexural (bending) strength can be achieved over plain concrete with higher dosage rates of shorter fibre products. • Fatigue Resistance – the fatigue strength of steel fibre concrete is far greater (1.6 times) than that of conventional concrete. • Impact– steel fibres greatly increase (1.5 to 5.0 times) concrete’s resistance to damage from heavy impact. • Shear Strength – shear strength is much improved (1.25 to 2.0 times) over unreinforced concrete. • Shrinkage– although the steel fibres themselves do not affect shrinkage rate, they can minimise and help eliminate shrinkage cracks, particularly in a restrained situation. • Abrasion– steel fibres do not affect the abrasion rate of concrete mortar itself. But they do offer a high degree (1.2 times) of protection against heavy duty abrasion and gouging. Spalling is dramatically reduced. • Permeability – again, steel fibres do not directly affec
