Compressive tests are carried out about mechanical properties of super high strength concrete exposed to fire as a part of experimental study. This paper presents basic data of thermal strain and total strain of super high strength concrete (water-binder ratio 18%, 24%, 35%) under constant stress and varying temperatures. The following results are obtained by this compressive tests. 1) An effect of water-binder ratio on thermal strain and total strain is little. 2) Super high strength concrete under constant stress and under varying temperatures shrinks more than normal concrete. 3) During a heating phase, increases of total compressive strain due to quantity of a constant stress on the specimen. On the other hands, during a cooling phase, variation of total strain is equal to decrement of thermal strain.
