ELECTRICALLY ACCELERATED METHODS FOR DETERMINING CHLORIDE DIFFUSIVITY IN CONCRETE - CURRENT DEVELOPMENT

In this paper, the theoretical background of electrically accelerated methods is reviewed, and the current development of the methods at Chalmers University of Technology is described. The rapid method based on the non-steady state process is emphasized and the advantages of this non-steady state method are summarized. A study of the method based on the steady state process is reported and some factors which influence the measurement are discussed. Some applications of these new methods in the research work on cement and concrete durability are mentioned. Parallel tests show that the new rapid method corresponds well with the conventional immersion test, although further study is needed to explain this coincidence. (A)
