“…Similar conclusions were drawn by the researchers, who discovered that the salt spray test caused more considerable coating degradation than natural weathering [19]. A similarity was observed only for exposure in marine environments [17,56].…”

Corrosion protection technologies based on waterborne paints have become increasingly popular as steel structure protection, which implies the need to determine relevant assessment methods considering the conditions of use and product-specific characteristics. This study attempts to evaluate the fitness of standard corrosion protection weathering methods and an original cyclic test for verifying the resistance of waterborne acrylic coatings to environmental conditions. Changes to the properties of artificially weathered coatings were analysed with reference to those observed during exposure in natural conditions. The degree of coating degradation after exposure to neutral salt spray and condensation humidity was determined to significantly exceed the changes observed in natural conditions. An original cyclic test caused changes in the appearance, microstructure, FT-IR spectrum and utility properties of the coatings, such as thickness, colour, hardness, adhesion and impedance, similar to those observed in the natural environment. The results confirm that the programming direction of waterborne coatings artificial weathering tests is adequate and promising.

“…Pan et al have studied the effectiveness of self-made imidazoline inhibitor on the durability of RC was systemically investigated and compared with the conventional triethylenetetramine inhibitor and concluded that that imidazoline and triethylenetetramine inhibitors can increase the corrosion potential to some extent. [64] Valcuende et al studied the corrosion resistance of the ultra-high performance concretes (UH) made with different fiber volume contents and under distinct curing conditions and concluded that UHs give excellent performance due to their high resistance to chloride penetration and their excellent resistivity. [65] Naveen Kumar et al have studied to assess the initial corrosion behavior of thermo-mechanically treated rebar (TMT), corrosion resistant rebar (CRS) and fusion bonded epoxy coated rebar (EC) under controlled condition (CC) and in simulated marine environment condition (SME) and concluded that the benefit of EC is anticipated to increase the durability of RC structures, particularly when periodic decay is extended in the regions where chloride accumulation is heavy and at that point deterioration of RC structures will become a considerable fit out.…”

Corrosion is the irreversible, interfacial reaction of metals in the presence of an electrochemical environment which ultimately results in the deterioration of metals. Corrosion of reinforcement is the major problem in the reinforced concrete (RC) structure. Corrosion of reinforcement is a slow process because of the protective layer of concrete. Even in a severely corrosive environment corrosion process takes time to be initiated and propagated. Since to carry out research work, some techniques are required to accelerate the corrosion process in the shortest period. To overcome this problem, in the past, many researchers use a different method to accelerate the corrosion of steel in concrete. In this paper, a review is presented of various techniques used for accelerated corrosion testing. The suitability of reviewed methods on corrosion acceleration for several research works is presented. After that few case studies review to make use of various predicted empirical models and an experimental technique for predicting corrosion rate and the assessment of the remaining life of the structure. And finally, the paper is concluded by comparing the natural method of corrosion and the accelerated method of corrosion and the future scope of accelerated corrosion.
