Title:
METHOD AND SYSTEM FOR MEASURING LENGTH CHANGE OF SAMPLE
Document Type and Number:
Japanese Patent JP2002048514
Kind Code:
A
Abstract:
To inexpensively and precisely measure a length change of a mortar or a concrete without requiring labor.
Two sheets of targets 10 are separately set in a sample 100 along the longitudinal direction, the samples 100 are arranged plurally alignedly, a guide rail 31 for guiding a laser displacement gage 20 is provided along the arrangement of the samples 100, the positional change with the lapse of time of the target 10 is measured by the laser displacement gage, and the laser displacement gage 20 is moved along the guide rail 31 to change the sample 100 as the measuring target. When set relatively shifted in the width direction, the respective targets 10 are measured by the same laser displacement gage 20.
