EFFECTIVENESS OF RANDON FIBRES IN FIBRE-REINFORCED CONCRETE

A more rational formula is proposed for the average spacing of randomly placed short lengths of wires, as compared with continuous fibers, than the one existing. The merits of the formulae are shown in the test results of cracking strength of steel fibre-reinforced composites with cement mortars. Also, an expression for the fracture toughness (an indirect measure of tensile strength) of concrete with short lengths of wires is derived and compared with the previous one with the help of test results obtained by the authors. This approach is helpful for other composite materials. /Author/
