The measurement of majority conventionally is methods to use the accelerometer having wire or cable in order to measure the acceleration on fresh concrete compacting into the form. There is not the measurement of the acceleration on fresh concrete compacting using the RFID （radio frequency identification） tag with the wireless capacitance-type acceleration sensor until now.
In this study, it was carried out the measurement of acceleration transmitted from the outside vibration machines on the fresh concrete compacted in the form of the precast concrete product with help of the RFID tag having wireless capacitance-type acceleration sensor for the first time in the world. The resultant acceleration measured does not depend on value of the slump and slump flow. The resultant acceleration measured was larger as the distance to the position of the outside vibration machine was closer and regardless of differences such as product shape and the filling height. The difference of maximum resultant acceleration by the damping action from the position of the outside vibration.
