Abstract
Freezing and thawing properties of cement paste were studied using an alternating current impedance spectroscopy (ACIS) technique coupled with the thermomechanical analysis (TMA). The measurements from the ACIS were analyzed in association with the length change of the cement paste determined by TMA. The micro-scale behavior of cement paste observed by the ACIS technique was well correlated with the residual expansion of cement paste after the freezing and thawing cycle. The efficacy of the ACIS technique for assessing the durability of cement paste to frost action was confirmed.
