摘　　要：综合论述了混凝土在不同环境条件下水分迁移机理与理论模型 ,以及国外在该领域的最新研究进展 .指出了对高性能混凝土必须考虑自干燥效应对非线性水分扩散方程的修正 。This paper deals with comprehensively moisture transfer mechanism, theoretical model in concrete in different ambient conditions and the latest research progress. It is pointed out that self desiccation effect shall be considered in modifying non linear water diffusion equation for high performance concrete. The judgments of fundamental problems of moisture transfer for high performance concrete and research focus for the future in this field are also presented.
