| Abstract: | A set of equipment was developed to study the concrete cracking in different climate condition considering the temperature,humidity and wind speed influence. The climate sensitivity factor of concrete cracking is used to indicate the influence of climate change to concrete cracking, which can be used to select the mix proportion of concrete with high suitability to climate in the channel concrete lining. This method is success-fully applied in concrete mix proportion optimization of Yangzi River crossing project of the east line of South-to-North Water Transfer Project. |
