抄録

<p>This study describes the methodology for measuring the thermal deformation of concrete specimens. Specimens should maintain a saturated state for preventing strain change by moisture content and we conducted strain measurement with temperature changes considering the underwater environment. The strain gauges were waterproofed to protect from moisture. To calibrate the thermal output of the strain gauges, we corrected the strain measured on the specimens by using additional dummy gauges. In addition, to obtain the strain of cement paste itself accurately, the measurement location of the specimen should be considered by the distribution of aggregates and the shape of the specimen.</p>
