摘要： The present invention provides a defect detecting/degree-of-filling-in measuring apparatus for concrete during placement that meets the tolerance for butting angle for the electrode with respect to the concrete form, and that is capable of carrying out measurement with the measurement depth being changed. The defect detecting/degree-of-filling-in measuring apparatus for concrete of the present invention comprises a detection section 42A for deeper-part measurement having a positive electrode 3 which surface to be butted against the concrete form is a curved surface and which is disposed in the middle portion of one end face of a cylindrical insulator, and a negative electrode 4 which is disposed at the other end face of the cylindrical insulator, being opposed to said positive electrode 3; and a detection section 42B for closer-part measurement having a spacing between the positive electrode 3 and the negative electrode 4 that is smaller than that for detection section 42A for deeper-part measurement at both ends of a gripper 41; determines the electrostatic capacitance corresponding to the deeper-part and the closer-part of the concrete during placement by means of the deeper-part measuring circuit and the closer-part measuring circuit; determines the degree of filling-in for the deeper part and the closer part for the object under measurement by means of the arithmetic circuit; further determines whether the moisture content and the concrete filled-in quantity for the concrete during placement are adequate; and displays the result in the display section 46.
