含冰量是影响水泥基材料冻融循环过程中水压力的重要因素，尤其是对混凝土结构的寿命预测具有重要意义。由于砂浆的电阻率与含水量密切相关，因此可以根据电导率的变化来估计含冰量。本文介绍了用电测法测定混凝土含冰量的方法，阐明了温度和饱和度对混凝土电导率的综合影响。
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.
