For the purpose of strength evaluation and damage evaluation the piezoelectric sensor based wave propagation technology is based experimentally done in the laboratory using the specified equipment and experimental setups. The energy attention of stressed wave measured on the basis of relative index between output voltage of piezoelectric sensor and the excitation voltage at actuator (ZHU Jinsong ,et al, 2010)on the basis of experimental output of concrete cubes the effect of impedance amplitude, excitation frequency , path of propagated wave and curing time of the output signature of sensors are evaluation relative voltage attenuation coefficient RVAC is used as indicator for measuring the attenuation of stress waves of concrete cube as a result.
