Abstract
This study was conducted for Ø100 × 200 mm specimens. The experiment was conducted at 20-700 ºC in the state that the loads of 0, 20 and 40 % of compressive strength at room temperature were applied. The evaluation items included thermal strain, total strain and transient creep subjected to high temperature. The results of experiments showed that it was found that the transient creep by loading is constant regardless of the type of aggregate below 500 ºC. However over 500 ºC, the higher the thermal expansion coefficient of aggregate is, the transient creep by loading increases rapidly.
