Abstract

The influence of ionic concentration of pore solution and matrix porosity on high frequency resistance (HFR) of hydrated cement paste were carefully studied. A new relation between HFR and porosity has been derived and its validity demonstrated by a series of experiments. A better description of the intrinsic value and physical meaning of HFR is presented. A convenient means of characterizing microstructural development in hydrating cement or concrete systems is provided by the A.C. impedance technique.
