1. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures
Abstract : Reinforced Concrete (RC) is the most common construction material in existing structures. However, RC structures are susceptible to deterioration over time, with corrosion of the reinforcing steel as most common mechanism. Corrosion reduces strength and ductility provided by the reinforcement bars and affects their interaction with the concrete. READ MORE

2. Natural corrosion in reinforced concrete structures
Abstract : Among the threats to the durability of concrete structures, corrosion of the reinforcement bars is undoubtedly the most common one. Corrosion damages impair safety and durability of infrastructure, and assessment of the safety is challenging due to the complex nature of the corrosion process. READ MORE

3. Corrosion of steel bars in fibre reinforced concrete: corrosion mechanisms and structural performance
Abstract : The viability of employing fibre reinforcement to improve the durability performance of RC structures by delaying and/or reducing rebar corrosion and by mitigating the structural impact of corrosion-induced damage have been investigated. Given the enhanced crack control of FRC, it could be advantageous to use fibres in civil engineering structures to decrease the ingress of corrosion-initiation substances. READ MORE

4. Chloride Induced Corrosion of Steel Bars in Fibre Reinforced Concrete
Abstract : Chloride-induced corrosion of reinforcement is the most widespread degradation mechanism affecting the durability of reinforced concrete structures. Macro-cracks provide a preferential path for moisture, oxygen and Cl ions to reach the embedded reinforcement, playing a major role in their total transport. READ MORE

5. Multiscale Modelling of Reinforced Concrete
Abstract : Since concrete cracks at relatively low tensile stresses, the durability of reinforced concrete structures is highly influenced by its brittle nature. Cracks open up for ingress of harmful substances, e.g. chlorides, which in turn cause corrosion of the reinforcement. READ MORE
