Abstract: The ingress of the harmful substance in the marine environment is main reason to cause the degradation of properties in the marine structures .This paper presents a review of research on the effect of the alkali-aggregate reaction on the properties of structures under marine environment from four aspects,i.e.the influence factors of the alkali-aggregate reaction expansion , the swelling behavior of alkali aggregate reaction , the chloride ion diffusion and chloride ion binding behavior , the mechanical properties damage and damage model under the combined action of the chloride ion and the alkali -aggregate reaction.Also,the existing problems in this study field are analyzed .The new research ideas on the effect of alkali-aggregate reaction on the properties of structures under marine environment are proposed.First,the new parameter must propose to more accurately reflect material damage degree under the alkali-aggregate reaction .Second , the study on the evolution of the long-term of the mechanical properties under the combined action of the chloride ion , the alkali-aggregate reaction and multi-dimensional stress need to increase .Finally,the constitutive model of concrete damage under three axis stress state is established .
