Title:
コンクリート内部の相対湿度の測定方法
Document Type and Number:
Japanese Patent JP7245046
Kind Code:
B2
Abstract:
To provide a method of simply and accurately measuring the relative humidity in concrete.SOLUTION: The present invention is a measuring method of the relative humidity in concrete and includes at least processes (A) to (C). (A) A specimen producing process: a plurality of concrete plates are cut out from a circular column or rectangular column of the concrete, then the peripheries of the plates are sealed with rubber rings (rubber ring), thereby producing specimens. (B) A specimen installation process: the specimens are installed into a plurality of grooves disposed inside a formwork in the circumferential direction, then humidity sensors are disposed between the specimens. (C) A relative humidity measuring process: a formwork having a plurality of grooves disposed on the same inside in the circumferential direction is covered on the installed specimens and sealed, then the relative humidity is measured.SELECTED DRAWING: Figure 7
