| Abstract: | The structure and performance of the large cryogenic-temperature storage for cooling reinforced concrete members and prestressed reinforced concrete members was described in this paper.Moreover,temperatu rereduction experiments and heat insulating experiments of reinforced concrete beams were carried out.Results of the experiments show that the storage is competent for the cooling and heat insulating task of reinforced concrete members and the temperature can be cooled down to-100℃.With more specimens to be cooled,more time is needed. |

| Keywords: | cryogenic-temperature reinforced concrete members temperature reduction experiment |
