| 摘 要： | 研究了相同配合比下不同长径比和不同品种钢纤维对层布式钢纤维混凝土的弯拉强度和韧性影响规律，分别运用日本JCI和美国ASTM韧性指数法计算各层布式钢纤维混凝土的韧性，结果表明层布式钢纤维混凝土具有良好增强和增韧双重效应。最后比较各种纤维的优劣，从中选取较佳纤维。

| Abstract: | Flexural strength and toughness of LSFRC whose steel volume fraction and type of steel fiber varying has been experimentally studied on the same mix.The toughness indexes of LSFRC were calculated by the ASTM method and the JCI method.The test results show that LSFRC has dual efforts of increasing strength and increasing toughness.Finally,LSFRC of different fibers were compared in order to choose the better fiber. |

| Keywords: | layered steel fiber reinforced concrete(LSFRC) flexural strength first-crack strength toughness indexes |
