Protective Coating for Concrete Structures

SiC protective coating for photovoltaic retinal prosthesis.

OBJECTIVE To evaluate plasma-enhanced, chemically vapor deposited (PECVD) amorphous silicon carbide (α-SiC:H) as a protective coating for retinal prostheses and other implantable devices, and to study their failure mechanisms in vivo. APPROACH Retinal prostheses were implanted in rats sub-retinally for up to 1 year. Degradation of implants was characterized by optical and scanning electron mi...

Coating Selection and Important Properties of Coatings for Concrete

Reasons for Coating Concrete Some reasons for coating concrete are unique to the structures in question while other reasons apply to coating any substructure. The major reasons for coating concrete include • enhancing appearance with respect to colour, gloss, or texture for architectural purposes; • reducing moisture permeability, which can otherwise lead to freeze-thaw damage, rebar corrosion,...

Structural Health Monitoring Paradigm for Concrete Structures

Structural health monitoring has been one of particular concerns of the engineering community. Effective monitoring, reliable data analysis, rational data interpretation and correct decision making are challenging problems for engineers who specialized in structural health assessment field. Concrete structures were constructed for various purposes in a certain design life in the context of 'mai...

Durability of FRP rods for concrete structures

Over the last two decades fiber-reinforced polymer (FRP) rods have emerged as one of the most promising and affordable solutions to the corrosion problems of steel reinforcement in structural concrete. The application of FRP rods in new or damaged structures requires the development of design equations that must take into account the mechanical properties and the durability properties of FRP pr...
