【摘要】 在混凝土中掺入适量的聚丙烯微纤维,能改善混凝土的脆性破坏特征,减少混凝土的收缩裂缝,提高混凝土的韧性、抗冲耐磨性。还能提高混凝土的抗渗、抗冻等特性,是实现混凝土高性能化的很好途径。结合杜拉纤维混凝土在西霞院反调节水库工程中应用的实践,对纤维混凝土在水利工程建设当中的实际应用情况进行了阐述。更多还原

【Abstract】 Adding right amount of polypropylene micro-fiber in concrete can improve the brittle failure feature of concrete, decrease the contraction crack of concrete, and enhance the toughness and anti-flush within hard-wearing. The measure can also enhance concrete characteristics, such as the anti-seepage and frostresisting etc. So it is a good method to enhance the concrete performance. Combining the application of the fiber reinforced concrete of Du La in the Xixiayuan Re-regulating Reservoir project, the fiber reinforced concrete applied in construction of hydraulic engineering was expounded in the paper.更多还原
