Abstract
The influence of ionic concentration of pore solution and matrix poros ity on high frequency resistance (HFR) of hydrated cement paste were c arefully studied. A new relation between HFR and porosity has been der ived and its validity demonstrated by a series of experiments. A bette r description of the intrinsic value and physical meaning of HFR is pr esented. A convenient means of characterizing microstructural developm ent in hydrating cement or concrete systems is provided by the A.C. im pedance technique.
