Strengthening Of Corroded Steel Structures Using Cfrp – An Experimental Review, Ghada El-Mahdy Ph.D., P.Eng, Abdallah H. Yassin, Abdel El Rahman Khaled
Civil Engineering
Fibre reinforced polymers (FRP) have been widely used to strengthen reinforced concrete structures, however, nowadays their use to strengthen steel structures is under investigation. In particular, the need to strengthen corroded steel structures found in aggressive environments, such as marine environments, which have undergone a reduction in cross-sectional area and hence a reduction in their load-carrying capacity is in need of studying. The main problems that arise when using carbon fibre reinforced polymer (CFRP) sheets to strengthen steel structures is the weakness in the interfacial bond between the CFRP and the steel surface, the thinness of CFRP sheet, and the …

Cysteine As An Eco-Friendly Corrosion Inhibitor, Hany A. Elazab Dr
Chemical Engineering
In this paper, the aim was finding the most efficient corrosion inhibitor for mild steel placed in a 0.5M Sulfuric acid. The comparison was implemented between Cysteine (an eco-friendly corrosion inhibitor) and 4 different Ions-Cysteine Inhibitors (Copper- Cysteine, Nickel-Cysteine, Iron-Cysteine, and Cobalt-Cysteine). The solutions were prepared and evaluated while placed with a working electrode of mild steel with a copper rod attached to its end. To determine the best eco-friendly corrosion inhibitors two experiments were implemented: Electrochemical Impedance Spectra, and Linear Polarization. By the end of the experiment it was found that Copper- Cysteine was the most efficient eco-friendly corrosion …
