This paper presents a series of experimental studies about the influence of environmental waters on static strength of concrete, and analyzes the physical mechanism that static strength of wet concrete would decrease. Overall, it is pointed out that most of the present research is qualitative explanation, and quantitative research is rather less. Moreover, it is suggested that the impact of the interaction of several factors on static strength of concrete should be studied, and the finite element analysis method should be used to simulate the link coupling on each interface of wet concrete.
