PROBLEM TO BE SOLVED: To provide a method capable of quickly and correctly determining compaction property of fresh concrete.SOLUTION: Compaction property of fresh concrete, which is the subject of compaction, is determined through a step of obtaining vibration acceleration and vibration angular velocity of a rod-like vibrator 10 on the basis of a current value of the rod-like vibrator 10; a step of obtaining fluid force received by the rod-like vibrator 10 with the use of the vibration acceleration and the vibration angular velocity; and a step of obtaining a viscosity coefficient of the fresh concrete with the use of the fluid force. 【課題】 迅速かつ正確に、フレッシュコンクリートの締固め特性を判定することが可能な方法を提供する。【解決手段】 棒状バイブレータ１０の電流値に基づいて、当該棒状バイブレータ１０の振動加速度及び振動角速度を求めるステップ、振動加速度と振動角速度とを用いて、当該棒状バイブレータ１０が受ける流体力を求めるステップ、流体力を用いてフレッシュコンクリートの粘性係数を求めるステップにより、締固め対象であるフレッシュコンクリートの締固め特性を判定する。【選択図】図１０
