MODELING SHIELDING EFFECTIVENESS FOR COMPOSITE WALLS OF CONCRETE AND CARBON FILAMENTS
Progress 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]
ISRN 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.

Functionalized Carbon Reinforcement Structures with Optical Fibre Sensors for Carbon Concrete Composites [PDF]
2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019 Here we present our latest efforts in the development of functionalized carbon reinforcement structures (FCSs). FCSs are textile based carbon structures that are functionalized with optical fibre sensors and are designed for the reinforcement as well as structural health monitoring (SHM) of concrete composites. A schematic of a FCS is shown in Fig. 1a.

Thin Bonded Overlays with Carbon Reinforcement for Concrete Pavements [PDF]
MATEC Web of Conferences, 2022 Here a possible alternative joint design in plain concrete pavements was investigated. The basis for this is to cover the concrete pavement with a thin jointless carbon reinforced concrete layer (CRC layer) of 50 to 70 mm as the top concrete.
