What properties of the concrete are improved by using Steel Fibres?
Steel fibre reinforced concrete acts as a uniform composite material. Compared to plain or conventionally reinforced concrete, the most immediate differences are improved ductility and post-crack performance. However, the specific effects on matrix mechanical properties greatly depend on the type and quantity of fibre used. Generally speaking, smaller fibres with a high fibre count offer superior first-crack strength and better fatigue endurance. Should a crack open widely, longer fibres with mechanical anchorage mechanisms offer better post-crack performance. back to the top 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. • Imp
