Abstract
In this study, nanochannels were prepared on a glass plate and the dependence of the chloride ion transport rate on the channel size was investigated. The nanochannels were etched using acidic etching agents, and the fluorescent reagent N-[ethoxycarbonylmethyl]-6-methoxy-quinolinium bromide (MQAE) was used to measure the concentration of the chloride ions. A decrease of the chloride ion transport rate with decreasing cross-sectional channel size was confirmed. The obtained results are, however, not directly applicable to concrete because glass and concrete have different surface properties. As such, a hardened cement paste (HCP) plate with a smooth surface and an absence of detected pores was prepared by high pressure curing. A microchannel was machined on the plate surface and a glass plate was bonded to this surface by autoclave treatment.
