| Abstract: | Flexural-tensile properties of normal concrete and layered steel fiber reinforced concrete and layered hybrid fiber reinforced concrete are contrasted.The effect of length-diameter ratio and volumetric fraction of steel fiber on flexural-tensile property of steel fiber reinforced concrete are experimentally studied.The results show that layered steel fiber and polypropylene fiber improve the flexural-tensile strength of concrete. |
| Keywords: | layered steel fiber reinforced concrete layered hybrid fiber reinforced concrete flexural-tensile strength length-diameter ratio volume fraction |
