Abstract
The present invention relates to the field of material determination or analysis, and provides a method of assessing drying depth of cementitious materials including the following steps: preparing a plurality of cementitious material specimens; drying the cementitious material specimens; conducting electrochemical impedance spectrum measurement on each cementitious material specimen; accordingly determining a model for analyzing the drying depth of the cementitious material specimen. The method of assessing drying depth of the cementitious material provided by the present invention takes the influence of the resistivity changes on the model into consideration, and the drying depth of the cementitious material is reflected and reckoned with regularly changes of the electrochemical parameters, not only increasing the accuracy but also saving much testing labor, time and cost.
