混凝土温湿耦合研究

Summary of Coupled Temperature and Moisture Transfer of Concrete

综述了混凝土温度与湿度耦合问题的研究成果与工程实践经验,分析了混凝土温湿耦合问题的主要特点,比较了线性耦合理论与非线性耦合理论的差别.就涉及早龄期混凝土表面开裂问题的混凝土温湿耦合机理进行了讨论.

Theoretical works and engineering practice on coupled temperature and moisture transfer conducted by pioneers, as well as ourselves, are summarized. The characteristics of coupled temperature and moisture transfer for civil engineering is presented and discussed. As for earlyage concrete, it is pointed out that such problem involved in surface cracking is more complex than ever estimated before, so apart from analyzing the coupled effects of temperature and moisture, it is necessary to carry out related tests, such as tests on the concrete creep and elastic modulus at its very early age.
