摘要
从表面热力学角度讨论了钢纤维砂浆的界面电容和表面自由能.通过串联阻抗的测量和电毛细方程的计算,可以确定界面电容对钢纤维砂浆力学性能的贡献.
Mechanical properties of steel fiber mortar is partly originated from the coulombic interaction of the interface between steel fiber and mortar. The capacitance of steel fiber mortar interface and the surface free energy are measured and discussed on the basis of surface thermodynamics. The contribution of interface capacitance to mechanical properties of steel fiber mortar can be analyzed through the measurement of impedance in series and the calculation of electro-capillary equation.
