A review on stray current-induced steel corrosion in infrastructure

Metallic corrosion can cause substantial damage at various levels and in almost all types of infrastructure. For metallic corrosion to occur, a certain external environment and the presence of corrodents are the prerequisites. Stray current-induced corrosion, however, is a rather underestimated issue in the field of corrosion and civil...

Properties of the steel-mortar interface derived by impedance spectroscopy in different environment and curing conditions

In practice, reinforced concrete structures may encounter different kinds of curing conditions<br/>due to the weather (sun radiation, air moisture and wind), nearby external environment<br/>(seawater, attack of stray current arising from nearby railways), or human factors (insufficient<br/>curing period). In some extreme conditions, the...

Effect of corrosion on the fatigue service-life on steel and reinforced concrete beams

Chloride-induced corrosion is a point of big concern in reinforced concrete (RC) structures. To monitor the actual health and to predict the remaining service-life of structures, it is important to understand the structural behaviour and the failure mechanism of structures exposed to chlorides under fatigue loading conditions. A beam test,...

Bio-inspired control of material properties in civil engineering: Current concept for corrsoion protection via the application of bacteria and bio-polymers

The improvement of material properties of cement-based materials e.g. reduced permeability, porosity, uniform distribution of hydration products, etc. is of a significant importance and related to durability and sustainability of concrete and reinforced concrete structures. With this respect, a recent and novel approach is to "create" self...
