The long-term durability of concrete structures is closely related to the physical and chemical properties of the structural concretes.This paper investigates the fundamental properties of durability for structural concretes.To this purpose, the gas permeability, chloride diffusivity, electrical resistivity and surface sorptivity are measured for several structural concretes with typical cementitious materials.The gas permeability is measured by CemBureau device, the chloride diffusivity is measured by NT Build 492 method, the electrical resistivity is measured by the alternative current method and the surface sorptivity by ASTM C1585 method.The relationships among these transport properties are explored through Archies law and Katz-Thompson equation,and the relevant parameters are determined.Moreover, with the pore structure characterized for these concretes,the relation between the pore structure and the measured transport properties is further explored.From the study,the gravimetry porosity is found to be the fundamental durability indicator, the electrical resistivity shows good stability of measurement, the formation factor from electrical resistivity shows good correlation with the porosity and the liquid intrinsic permeability predicted from Katz-Thompson equation is two orders of magnitude lower than the gas intrinsic permeability.
