摘　　要：A non contacting electrical resistivity measurement device was used for measuring the electrical resistivity of cement paste incorporated with retarder.The hydration process was divided into dissolving period,setting period,hardening period.With the increase of the retarder,the dissolution time will increase.The setting time happens between minimum point time and inflexion point time based on the electrical resistivity curve.The strength isoline was proposed to predict the strength trend.A non contacting electrical resistivity measurement device was used for measuring the electrical resistivity of cement paste incorporated with retarder.The hydration process was divided into dissolving period,setting period,hardening period.With the increase of the retarder,the dissolution time will increase.The setting time happens between minimum point time and inflexion point time based on the electrical resistivity curve.The strength isoline was proposed to predict the strength trend.
