Special Issue Information

Dear Colleagues,

In this Special Issue, we welcome submissions of original research, case studies, reviews, and state-of-the-art discussions that focus on the corrosion resistance of reinforced concrete.

Studying corrosion resistance is crucial in civil engineering and materials science. Corrosion can significantly damage reinforced concrete structures and cause durability issues, leading to expensive repairs and maintenance. This Special Issue aims to extend the durability of reinforced concrete structures, reduce maintenance costs, and ensure the safety and continuity of infrastructure. However, accomplishing this goal frequently requires an interdisciplinary approach incorporating materials science, mechanical engineering, civil engineering, chemistry, and environmental science. Moreover, the ongoing advancements in materials and technologies are persistently driving progress in the field of corrosion prevention in reinforced concrete. Indeed, this continually evolving area demands accuracy and extensive research to achieve ecologically and scientifically sound outcomes.

Some potential key aspects and topics that researchers typically explore in this field include, but are not limited to:

  • Corrosion Mechanisms;
  • Concrete Mix Design;
  • Corrosion Protection Methods: corrosion-inhibiting admixtures, protective coatings, cathodic protection, alternate steel rebar, surface treatments/coating, sustainable and eco-friendly materials;
  • Corrosion Monitoring Techniques;
  • Environmental Factors;
  • Microstructure Analysis;
  • Modeling, Simulation and Life Cycle Assessment;
  • Case Studies and Durability Assessment;
  • Repair and Rehabilitation.

The corrosion of steel rebar embedded in concrete under marine conditions is a major global concern. Therefore, it needs a proper corrosion mitigation method. Various types of corrosion inhibitors are used to mitigate the corrosion of steel rebar in chloride-contaminated concrete; however, selecting the appropriate inhibitor and determining its optimal concentration remains a concern. Therefore, in the present study, three types of inhibitors—calcium nitrite (CN: Ca(NO2)2), N,N′-dimethyl ethanol amine (DMEA: (CH3)2NCH2CH2OH), and L-arginine (LA: C6H14N4O2) in three different concentrations, i.e., 0.3, 0.6 and 1.2 M—were compared with a control (without inhibitor, i.e., blank) sample to determine the optimum concentration of the inhibitor for corrosion resistance performance evaluation of reinforcement bars immersed in 0.3 M NaCl-contaminated concrete pore (NCCP) solution for various durations. The corrosion resistance properties were assessed using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) with immersion duration, and potentiodynamic polarization (PDP) after 168 h of exposure. The results showed that the CN inhibitor performed exceptionally well (corrosion inhibition efficiency greater than 97%) in terms of corrosion resistance. However, due to its hazardous nature and its ban in the U.S. and European Union, CN cannot be used in construction. In comparison, while DMEA showed some effectiveness, LA performed better and is also eco-friendly. The corrosion resistance efficiency of samples containing 0.6 M LA remains above 97% even after 168 h of immersion in the NCCP solution. This efficiency is consistent throughout the entire immersion period, from 1 h to 168 h. Therefore, it is recommended that LA be used as a corrosion inhibitor for steel reinforcement bars instead of CN, particularly in chloride-contaminated concrete, as it is both effective and safer than CN.
