Abstract: Resistivity of concrete in a structure can be measured relatively easily, and is important with respect to steel corrosion rate. Further interpretation of such data is not easy, since the resistivity for a given concrete varies strongly with temperature, water content and conductivity of the pore water. Resistivity for a number of 12-year-old high performance concretes were measured in the laboratory as functions of water content and temperature. Such data is essential to obtain more information from field monitoring, for example the moisture variations which are central to all durability related issues for concrete structures.
