| 摘 要： | 采用短切浸胶玄武岩纤维,按0、1、2、3、4、5 kg/m3等不同纤维掺量制作玄武岩纤维混凝土试件,进行了抗压强度、劈裂强度和抗折强度试验,研究了不同掺量与强度之间的关系。当纤维掺量为4 kg/m3,抗压强度提高率为46.3%;当纤维掺量为3 kg/m3,劈裂强度提高率为27.3%,抗折强度提高率为25.0%。试验结果表明,掺加玄武岩纤维后混凝土抗压强度、劈裂强度和抗折强度提高较明显。

| Abstract: | The chopped dipping basalt fiber was used to produced concrete test specimen of fiber content about 0,1,2,3,4,5 kg/m3.The compression test,splitting test and bending test were carried out to study the relationship between content and strength.When the content of fiber is 4 kg/m3,the increasing rate of compression strength is up to 46.3%.When the content is 3 kg/m3,the increasing rates of splitting strength and bending strength are 27.3% and 25.0% respectively. |
