| Abstract: | The origin of high temperature bursting in concrete is summarized in this paper. Also, the testing methods of for investigating the internal steam pressure at high temperature, how to reduce the internal steam pressure in concrete, and the approaches to improve the burst resistance of concrete at high temperature are reviewed. Three measures are proposed to prevent the high temperature bursting of concrete which will be beneficial to the high temperature bursting study of concrete. |
