PROBLEM TO BE SOLVED: To provide an effective formwork to be used in a method to perform highly accurate management of quality determination, formwork removal timing determination, formwork removal timing setting, lifetime estimation, and construction information.SOLUTION: A resistance value measurement formwork for placed concrete includes: pairs of a plurality of electrodes arranged to be arrayed at specified equal intervals while being protruded into the formwork so that at least one end of each is embedded in the placed concrete; electrifying means; and measuring means for measuring values for currents flowing in the respective electrodes and potential differences between the plurality of electrodes. The electrodes each having a part embedded in the placed concrete, in which an electrifying part for electrifying the placed concrete is kept exposed and a portion other than the electrifying part is kept insulated by and covered with an insulating member. The surface of the electrode at its portion equivalent to a desired electrification depth is kept exposed, thus enabling an electrification depth to be set by properly changing the position of the electrifying part according to a set value for the electrification depth. |
