摘要

PROBLEM TO BE SOLVED: To provide a unit water volume measuring device of freshly mixed concrete that can measure the unit water volume of the freshly mixed concrete speedily and easily and improve the measurement accuracy.;SOLUTION: The upper part of a sample container 1 for storing freshly mixed concrete P for an air capacity test (JIS A1128) is covered by a disk-like top cover 2 having a through hole 5 and insertion guide cylinder 3 in the center part. A rod-like sensor 8 is inserted into the through hole 5 and arranged in the center part of the sample container 1. The sample container 1 is mounted on a top plate 12 having 40 cm of height H from the lower end of a support body 13 and is measured. Thus, it can be measured speedily and easily accurately without being affected by hydrogen atoms such as moisture of a ground 19.;COPYRIGHT: (C)2006,JPO&NCIPI
