Theoretical Model for Estimation of Ice Content of Concrete by Using Electrical Measurements

Ice content is an essential factor that affects the hydraulic pressure of cement-based materials during freeze-thaw cycles (FTC), especially for predicting life cycle of concrete structures. Since electrical resistivity of mortar is in close relationship with moisture content, it is possible to estimate the ice content based on conductivity change. This paper presents the method using electrical measurements to obtain the ice content and clarifies the combined effect of temperature and degree of saturation for electrical conductivity of concrete.
