| 摘 要： | 以水泥砂浆为基体,多壁碳纳米管(MWCNT)为增强组分,采用不同的分散剂和分散方法制备碳纳米管水泥砂浆(MWCNTRM).通过对碳纳米管水泥砂浆标准试件的三点弯曲试验,研究了分散剂类型及其掺量、水灰比、碳纳米管掺加量对碳纳米管水泥砂浆梁弯曲性能的影响.结果表明:分散剂与碳纳米管的质量比存在一个临界值(分散剂为CTAB时... |

| Abstract: | In this article,fiber-reinforced Cement Mortar with multi-walled carbon nanotubes(MWCNTs) loadings were fabricated with different surfactant and dispersion method.It is shown that for effective dispersion the application of ultrasonic energy is absolutely required.The flexural behaviour of reinforced cement mortar beams with different surfactant and concentration,water cement ratio,concentration of MWCNTs were investigated by three point bending test.Results show that there exists an optimum weight ratio of... |
