Summary of Concrete Shrinkage and Creep Characteristics under Special Temperature and Humidity Environment |
| |
| Abstract: | In order to summarize the current research status of concrete shrinkage and creep under special temperature and humidity conditions, the method of literature survey and induction is adopted. The shrinkage and creep characteristics of concrete under constant or changing temperature and humidity are summarized respectively. And several classic shrinkage and creep prediction models and their construction methods are introduced. And measures to restrain concrete shrinkage and creep under special temperature and humidity environment are summarized. The analysis shows that the main research directions for this field in the future are to modify the classical model through experiments or simulations, and to explain the microscopic mechanism of shrinkage and creep in different environments. |
