The purpose of present paper is to study the influence of the properties, such as thickness or Cl^- diffusivity, of Interfacial Transition Zone (ITZ) between aggregate (fine and coarse aggregate) and cement paste. To accomplish this propose, the evaluation methods for determining the thickness and the Cl^- diffusion coefficient of ITZ were developed. Subsequently, these methods were used in the investigation to assess the influence of aggregate size on the thickness and the Cl^- diffusivity of ITZ formed. Moreover, the influence of ITZ formed around fine and coarse aggregate on the Cl^- diffusivity in concrete was clarified using the data obtained by above methods.
