The water content in cement mortar and flowing water in concrete were measured with CFGFRP (carbon fiber glass fiber reinforced plastics) composites used as electrodes. The electrical resistance and conductivi ty of cement mortar and concrete were influenced by frequency, applied voltage and temperature. The fre quency of 1 kHZ and applied voltage of 5 V were used for measuring in the present study. The conductivity of cement mortar decreased with decreasing water con tent. The conductivity of cement mortar and concrete increased in short tirne with adsorbing or flowing water. CFGFRP composites are promising as electrode of intenigent concrete structures measuring both water content and flowing water.
