Abstract
This study was directed towards examining the effect of steel fiber reinforcement on the flexural fatigue strength of f ibrous concrete matrices. Six different fiber types were considered, namely 0.75 and 1.0 in. x 0. 01 in . (1 . 91 and 2.54 cm. x 0.025 cm.) brasscoated wire, 0.50 x 0. 01 in . (1.27 x 0.025 cm.) wire, 0.75 x 0. 016 in~ (1.91 x 0.041 cm.) Duof orm wire , 1.25 x 0.023 in. (3.18 x 0.058 cm.) melt extract , and 0.01 x 0.0 2 x 1 . 0 in. (0 . 025 x 0.50 x 2.54 cm . ) sliced plate. Eight fibrous mixes and one plain concrete mix were cast on the basis of equal slump and equal cement content, and then tested to determine the effects o f volume concentration of fibers and aspect ratio on fatigue strength and deflection characteristics. Strength and deflection both increased significantly as fiber concentration and the product of volume concentration and aspect ratio, ~, increased. Static flexural and compressive strengths, flexure toughness , and the characteristics of flexural failure were also examined with regard to varying fiber concentration and aspect ratio. In each case, performance of the fibrous mix was compared with the plain concrete mix.
