Influence of Carbon Fibre Reinforced Polymer and Recycled Carbon Fibres on the compressive behaviour of self-compacting high-performance fibre-reinforced concrete [PDF]

open access: yesArchives of Civil Engineering, 2023
In recent years, carbon fibres have been extensively used to strengthen concrete structures. In most cases, the lamination process is carried out using epoxy resin as matrix.

MODELING SHIELDING EFFECTIVENESS FOR COMPOSITE WALLS OF CONCRETE AND CARBON FILAMENTS

open access: yesProgress In Electromagnetics Research M, 2013
Concrete walls reinforced with rebars have poor shielding efiectiveness for telecommunication frequencies (frequencies above 0.5GHz). An efiective method to increase the shielding efiectiveness of the walls is to increase the complex permittivity of the concrete. This can be done by mixing in thin fllaments of a material with high conductivity.

The Performance of Carbon Fibre Composites as ICCP Anodes for Reinforced Concrete Structures [PDF]

open access: yesISRN Corrosion, 2012
Cathodic protection has been proven to be one of the most widely applicable and cost-effective solutions for tackling steel corrosion in reinforced concrete. In this study, the possible use of carbon fibre composites, which are primarily used to strengthen concrete members, has been investigated as impressed current cathodic protection anodes.
