【摘要】 研究了不同玄武岩纤维掺量对C50防水混凝土抗压和抗折性能影响,并将试验结果与相同条件下聚丙烯纤维防水混凝土力学性能进行对比。试验研究表明:掺入玄武岩纤维和聚丙烯纤维后防水混凝土均表现出塑性破坏特征,试件抗压与抗折强度均有较大幅度提高。两种纤维对防水混凝土力学性能的影响规律基本一致。更多还原

【Abstract】 The influence of basalt fiber volume fraction on the compressive strength and the flexural strength of C50 waterproof concrete was investigated by experiments,and the test results were compared with those of polypropylene fiber waterproof concrete.Results showed that two kinds of concrete investigated herein both exhibited plastic failure mode,and the compressive strength and the flexural strength of concrete were improved obviously after adding fibers.Two kinds of fiber had the similar effect on mechanical properties of waterproof concrete.更多还原
