Abstract This paper investigates the interplay between corrosion of reinforcement and corrosion-induced cracking in reinforced concrete structures with non-uniform distribution based on experimental results a beam simultaneously subjected to sustained deflection accelerated through impressed current. Unlike previous studies, this work encompasses various refined techniques for measurement surfa...

Abstract In this work, an active protective epoxy coating with weathering resistant, corrosion-warning, and self-healing properties was developed by incorporating tannic acid (TA) loaded mesoporous silica (MSN-TA) nanocontainers. The introduction of MSN-TA nanocontainers could alleviate the degradation via scavenging radicals generated during UV irradiation. Compared blank coating, containing 5...

The corrosion resistance of fly ash-based geopolymer structural concrete (GPC), with or without fibers, was investigated in a simulated marine environment, and compared that ordinary Portland cement concrete. behavior is studied through an electrochemical method for inducing accelerated corrosion. fiber reinforced beam specimens contained polyolefin fibers the amounts 0.1%, 0.3%, 0.5% by volume...

In most structural failures, deterioration of reinforced concrete structure is due to corrosion reinforcing bars. Ingress chloride ions and reaction carbon dioxide with the cement paste poor-quality or inadequate cover are main causes corrosion. Corrosion can be reduced by using high-quality providing proper reinforcement. addition, inhibitors used protect reinforcement in order extend service ...

Cross-river bridges located in seismically active areas are exposed to two major natural hazards, namely earthquakes and flooding. As the scour depth increases, more parts of bridge substructure will inevitably be unfavorable conditions such as chloride ion (Cl−) corrosion. To investigate seismic performance highway under action Cl− corrosion, a spatial finite element dynamic model continuous r...

The evolution of the overall microstructure and contribution constituent second phase particles during accelerated corrosion AA 7075-T651 warrants further scrutiny. A correlative microscopy-based approach was employed to study damage in subjected potentiodynamic polarization. X-ray Computed Tomography (XCT) scanning electron microscopy were used track initiation propagation globally at specific...
