BOND STRENGTH OF STEEL FIBRE REINFORCED CONCRETE

Test results are presented to show that the Anchorage bond strength of deformed bars is 40% higher in steel fibre concrete than in plain concrete. The fibres were most effective in controlling cracking and failure of the test specimens. It is suggested that a steel fibre tensile skin can substantially improve the stiffness and serviceability conditions of conventionally reinforced structural members. The experimental work consisted of several pull-out tests on 10mm, 12mm, 16mm, 20mm and 25mm diameter bars embedded in steel fibre and plain unreinforced concrete. All the reinforcing steel were hot-rolled, high-yield deformed bars with a characteristic strength of 410 n/mm2 and were embedded either vertically or horizontally within the concrete. /TRRL/
