摘要:

在工作度试验研究的基础上，根据不同国际标准研究了不同类型纤维(钢纤维、聚丙烯纤维、混杂纤维)对自密实混凝土强度与抗弯韧性的影响．结果表明：混杂纤维可显著提高自密实混凝土的韧性并改善其破坏形态．

Abstract:

Based on the investigation on the workability of fiber reinforced self-compacted concrete (FRSCC), this paper analysed the influence of the types of fibers, including steel fiber, polypropylene fiber and hybrid fiber, on the compressive strength and flexural toughness according to different international guidelines. The effect of hybrid fiber on the toughness and failure patterns of self-compacted concrete is verified by the results of investigation.
