Abstract
In this work the dielectric properties of concrete with and without chlorid es as a function of their water contents were studied by the Electrical Imp edance Spectroscopy (EIS). Specimens of cement paste with different water/c ement ratio and chlorides content was analyzed. After drying the specimens, the rehydration was controled by the relative weight increasing. A detaile d study of the dielectric behavior in the range of 20 Hz to 40 MHz accordin g to the water and the chlorides contents was made. The results were discus sed in the framework of the material processes.
