摘要
PROBLEM TO BE SOLVED: To provide a quality determination method in the curing of cast concrete, which enables highly accurate quality determination and curing completion time determination by directly measuring concrete, as an actual structure, provided in a framework, which is in the course of curing, and also to provide a curing completion time determination method and quality determination framework.;SOLUTION: In a quality determination method in the curing of cast concrete, a plurality of electrodes in which each group is composed of four electrodes provided at specific equal intervals are disposed from outside a framework so that at least part of each electrode is embedded in the cast concrete. After the concrete is cast and cured, a specific resistance value of the cast concrete is calculated using a four electrode technique based on a value measured by applying a voltage from outside the concrete cast with respect to the electrodes. The progress of a hydrogen reaction of the cast concrete is grasped based on the thus obtained specific resistance value, thereby determining the quality.;COPYRIGHT: (C)2014,JPO&INPIT
