| 摘 要： | 通过27个混凝土与玄武岩纤维增强复合材料(BFRP)的粘结试件的单剪试验,考察树脂种类、混凝土强度、粘结长度等因素对粘结性能的影响.通过描述粘结界面破坏形态,测量BFRP与混凝土界面的应变分布规律,分析界面粘结应力的分布规律.结果表明,当混凝土强度在C20～C40的强度等级范围内,随着混凝土强度等级的提高,有效粘结长度稍微有所减少,可以确定为80 mm.

| Abstract: | Single shear tests of 27 specimens are conducted to investigate the bond properties between basalt fiber reinforced polymer and concrete,such as the effect of adhesive types,concrete strength and bond length.The interface bond failure forms are described,then the strain distribution between basalt fiber reinforced polymer(BFRP) and concrete is measured,and the distribution of shear bond stress between BFRP and concrete is analyzed.The test results indicate that: with increasing the concrete strength grade f... |
