| 摘 要： | 研究了碳纤维增强水泥砂浆的抗压强度、抗折强度、体积电阻率随纤维掺量变化情况,以及体积电阻率在轴向单调外力和循环外力作用下的变化情况。应用SEM观察了碳纤维增强水泥砂浆的微观结构。研究结果表明碳纤维水泥砂浆具有机敏特性,可以通过测量其电阻率的变化用来监测其受力情况。

| Abstract: | In this paper,we studied the compressive strength,flexural strength and volume resistivity changes of car- bon fiber reinforced cement mortar (CFRC) when the carbon fiber addition changed.The volume resistivity changes of CFRC under axial single compressive force and circle compressive force were investigated.Employing SEM meth- od,the microstructure of CFRC were observed.The test results show that the CFRC have smart properties,and the volume resistivity changes can be used to monitor the external force resulted on the CFRC. |
