<P>PROBLEM TO BE SOLVED: To provide a concreting management method and apparatus in which quality management of deposited concrete is made possible by grasping concreting situations continuously in real time. <P>SOLUTION: A level sensor 16 having a pair of electrode wires 1602 is disposed at an interval in a circumferential direction inside a mold 10 and while extending in a vertical direction of the mold 10 that is a finish height direction of concrete to be deposited. A change in electrostatic capacitance which is generated in accordance with a specific dielectric constant of concrete between the pair of electrode wires 1602 of the level sensor 16 is measured by a measuring circuit 18. On the basis of this measurement, strength management or quality management of deposited concrete such as concreting speed, the remaining quantity required for concreting into the mold, moisture content, cold joint or the like is made possible. <P>COPYRIGHT: (C)2012,JPO&INPIT |
