摘要: This paper summarizes the results of a research that has been carried out aiming to assess effects cement paste content on transport and electrical properties mortars using electrochemical impedance spectroscopy (EIS) method. Six mortar samples different proportions aggregate (different fractions) constant size were used. The microstructure investigated EIS method an equivalent circuit model, which allowed determining effectively physical behaviour conductive non-conductive pores. Some other experiments, such as compressive strength rapid chloride penetrability tests, also out. Results showed proper relationships between pore conductivity samples, explaining some complex among them. Additionally, volumetric fraction identified.
