Testing Verifies Creep Resistance of Steel Fibre ConcreteAs a world leader in steel fibre technology, Bekaert operates a fully serviced concrete laboratory capable of testing all types of fibre concrete beam and plate specimens.In 2003, a research project was initiated to verify the effects of creep within fibre reinforced concrete beams under continuous load. After a year of rigorous testing, Bekaert has published a technical note compiling the results of this programme.Concrete beams containing Dramix® Steel Fibres and two different macro synthetic fibres were tested in accordance with JSCE SF-4, the Japanese beam testing standard. The toughness values for all three specimens were comparable. One half the residual load at a 5 mm deflection was then applied and maintained for 1 year. The Dramix® Steel Fibre beams exhibited minimal creep and significantly, the creep deflections stabilized in less than 6 months. The macro synthetic fibre beams exhibited 7-20 times the amount of creep that occurred in the Dramix® reinforced beams. After 1 year of testing, creep continues to occur within the macro synthetic fibre beams indicating a continuing increase in crack width.The long term study will continue to fully analyze the effects of creep in fibre concrete.
