※ Measurement Condition: After repeatedly applying compressive load under specific temperature and pressure, measurement of the sample plate thickness was performed after each cycle under room temperature and the amount of change was taken as compressive creep. In addition, a test specimen was prepared from the sample after measuring its plate thickness, and compressive strength was measured under room temperature. < 20 sec./cycle (3 sec.

☆ ※ Measurement Conditions: After leaving the specimen in a atmosphere furnace of a specific temperature while still applying load, measurement of the sample plate thickness was performed after every interval of time under room temperature and the amount of change was taken as compressive creep . In addition, a test specimen was prepared from the sample after measuring its plate thickness, and compressive strength was measured under room temperature. E Compressive creep ... Dimensional change (settling) expressed as the rate of change, that occurs along the elapsed time in a specimen under a specific load (compressive force) applied in its thickness direction.
