It is known that properties of concrete, including the transport of moisture, depend on its microstructure, which can be modulated by chemical and mineral additives, termed as admixtures. In the previous report, the effect of admixtures, such as glycerol as a nanoviscosity modifier, was evaluated indirectly by measuring the corrosion rate of reinforcement steel. However, it was found that this method (corrosion) could be biased due to the effects of admixtures on corrosion inhibition per se. Therefore, there was a need to evaluate the concrete permeability by direct transport through its matrix. This was done in a new experimental design, which allows direct measurement of chloride concentration change with time. A concrete with particular admixture, and of disks geometry, separates two water compartments. Chloride concentration in initially pure water compartment is measured with time using ion chromatography. Kinetics of chloride transport now allows direct correlation to corrosion rate.
