Artificial Intelligence and Machine Learning Approaches for Corrosion Prediction and Management of Steel Reinforcement in Concrete: A Systematic Review
Abstract: Load bearing concrete structures need steel reinforcement bar (rebar), which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl−, SO42−). In recent models for the potential life span, the causes of failure of concrete structures have been established principally due to the chloride (Cl−) ion, because of the ease in transportation of Cl− in concrete and …

Review of Nitrite Inhibitor for Protection of Rebar Corrosion
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …

Use of Geopolymer Composites for Controlling Structural Cracks
Abstract: A building’s safety and stability can be compromised by ignoring the potential structural issues indicated by occurring cracks in buildings. Extensive damage may cause over the period from unidentified cracks.Good quality concrete never cracks in normal service conditions unless high horizontal force is applied. Through the cracks, carbon dioxide is released into the concrete and speeds up carbonation throughout the cracks, thus reducing the structure usage. The materials which are …
