ABSTRACT: The present study examines the
behavior of three major categories of organic coatings which are applied on the
surface of concrete structures and specifically conventional, high performance
and nanotechnology paint systems. The comparison is achieved in the means of
anticorrosion properties under the presence of chloride ions and carbonation resistance.
The evaluation methods included electrochemical measurements in order to assess
corrosion properties and the determination of steel’s mass loss after the end
of the experimental procedure. Carbonation depth was measured using
phenolphthalein as indicator after accelerated and physical exposure. From the
results so far it can be shown nanocoatings gave promising results regarding
induced chloride ion corrosion.
