Corrosion of steel reinforcement in an aggressive environment constitutes a serious problem for many reinforced concrete (RC) structures. Fiber-reinforced polymers (FRP) rebars represent a potential solution to this situation. Even if FRP reinforcement shows a good resistance to electro-chemical corrosion, long-term behavior must be investigated and proven. The mechanical properties of FRP rods...

Corrosion cracking of reinforced concrete caused by chloride salt is one of the main determinants of structure durability. Monitoring the entire process of concrete corrosion cracking is critical for assessing the remaining life of the structure and determining if maintenance is needed. Fiber Bragg Grating (FBG) sensing technology is extensively developed in photoelectric monitoring technology ...

Performance evaluation of implantable devices is not new to medical device manufacturers, specifically implant manufacturers. A focus on corrosion resistance of implant devices has prompted members of the medical device industry, along with the United States Food and Drug Administration [USFDA] to set forth a guide for performance testing. Although actual corrosion resistance of a material can ...

Reinforced concrete beams are normally designed as under-reinforced to provide ductile behaviour at failure i.e. the tensile moment of resistance, Mt(0), is less than the moment of resistance of the compressive zone, Mc. Since it is well established that the steel in reinforced concrete beams is prone to corrosion, the residual flexural strength is normally the main concern of asset managers. H...

DURING COMBUSTION in the gas turbine, sulfur from the fuel reacts with sodium chloride from ingested air at elevated temperatures to form sodium sulfate. The sodium sulfate then deposits on the hot-section components, such as nozzle guide vanes and rotor blades, resulting in accelerated oxidation (or sulfidation) attack. This is commonly referred to as “hot corrosion.” Sulfur in the fuel is gen...

Recently, countries from around the globe have been actively developing a new solar power system, namely, floating photovoltaic (FPV) system. FPV is advantageous in terms of efficiency and cost effectiveness; however, environmental conditions on surface water are harsher than ground, regulations standards for long-term durability supporting devices insufficient. As result, this study aims to in...

Corrosion of the embedded steel is one main degradation problems limiting service life reinforced and pre-stressed concrete structures. A model able to provide approximate predictions evolution cracking process can be useful for designing accelerated corrosion tests cement mortar or specimens. An electrochemical has been used describing inner displacements strains caused by accumulation product...
