Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for restraining occurrence of a cold joint or the like in the concrete placement work in layers. SOLUTION: The progress of the condensation of the concrete can be continuously grasped and the optimum time interval of the placement in layers of the concrete can be obtained by measuring electric conductivity of the concrete actually placed at the moment in order to restrain the occurrence of the cold joint.
