1. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures
Sammanfattning : 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. LÄS MER
2. Natural corrosion in reinforced concrete structures
Sammanfattning : 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. LÄS MER
3. Corrosion of steel bars in fibre reinforced concrete: corrosion mechanisms and structural performance
Sammanfattning : 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. LÄS MER
4. Chloride Induced Corrosion of Steel Bars in Fibre Reinforced Concrete
Sammanfattning : 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. LÄS MER
5. Multiscale Modelling of Reinforced Concrete
Sammanfattning : 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. LÄS MER
