Studies on the Evaluation of the Performance of two Types of Polyurethane Coatings on Steel Rebars for the Prevention of Corrosion in Concrete Structures
| Resumo: | The performance of two resin combinations, such as acrylic polyol - aromatic isocyanate and polyester polyol - aromatic isocyanate as durable and effective rebar coatings for steel in concrete has been examined by studying their mechanical properties and by using accelerated tests such as salt spray test and electrochemical impedance spectroscopy. It is found that polyester polyol-aromatic isocyanate combination performs better than acrylic polyol-aromatic isocyanate combination. Incorporation of fly ash in the coating is found to influence the performance of the coating. |
