| Abstract: | The effect of the aggregate type, strength grade, cooled way and the heating temperature on the mechanics performance of concrete was experimentally investigated. All the test results were compared with the relevant ones in room temperature. The decreasing degree of strength of concrete was got. This may be beneficial to the assessment and appraisal of RC structures after fire. |
