Abstract:

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.
