“…The pumice used in this study is coming from Gyali, a small volcano islet in the Dodecanese islands, which belongs to the southern Aegean volcanic arc. The south-western part of the islet is formed by pumice whereas the north-eastern part by obsidian domes and rhyolitic lava flows [6,7]. The pumice stone quarry is operated using the method of vertical benches and the quarry's production capacity in the form of natural pumice is up to 800.000 t/y.…”

“…At various points, the corrosion of reinforcement has reduced the diameter of rebar; therefore, the reinforcement must be cut and restored with new section of reinforcement. In this particular case, much attention was paid to the protection of reinforcements against corrosion and against carbonation in order to repair the tower [6,7]. The applied method of protection against corrosion was the use of organic coatings.…”

This study refers to the cooling tower of Megalopolis (construction 1975) and protection from corrosive environment. The maintenance of the cooling tower took place in 2008. The cooling tower was badly damaged from corrosion of reinforcement. The parabolic cooling towers (factory of electrical power) are a typical example of construction, which has a special aggressive environment. The protection of cooling towers is usually achieved through organic coatings. Because of the different environmental impacts on the internal and external side of the cooling tower, a different system of paint application is required. The present study refers to the damages caused by corrosion process. The corrosive environments, the application of this painting, the quality control process, the measures and statistics analysis, and the results were discussed in this study. In the process of quality control the following measurements were taken into consideration: (1) examination of the adhesion with the cross-cut test, (2) examination of the film thickness, and (3) controlling of the pull-off resistance for concrete substrates and paintings. Finally, this study refers to the correlations of measurements, analysis of failures in relation to the quality of repair, and rehabilitation of the cooling tower. Also this study made a first attempt to apply the specific corrosion inhibitors in such a large structure.

“…The mechanism of influence of these admixtures is complex and varies depending on the salt. Also, their use presents a major drawback to the change in certain physical properties of concrete (compressive strength, reduction hardened of cement) and their unproven effectiveness [1].…”

This paper examines the use of corrosion inhibitors in order to protect the reinforcement of concrete. For this purpose mortar specimens were constructed with or without corrosion inhibitors and were partially immersed in sodium chloride. Corrosion inhibitors were used as admixture into concrete and were sprayed on the external surface of mortar specimens. In all mortar specimens, electric junction between reinforcements was achieved. The methods that were used for the evaluation of the reinforcement corrosion in concrete, included half-cell potential measurements, polarization curves of reinforced rebars and mass loss of the reinforcement. Finally, the durability of concrete after the use of corrosion inhibitors was also examined.
