Electrical interactions between Cathodic Protection systems and surface- bonded CFRP composites in RC structures

Coventry University

Centre for Research in the Built and Natural Environment

Project Description

In practice, the application of cathodic protection systems in conjunction with CFRP- strengthening work to RC structures, is often required if the structural element remains exposed to a corrosive environment during its extended service life.

This project will seek to investigate the electrical and electrochemical interaction between carbon fibre composite strengthening system and CP system and develop suitable method(s) to mitigate the potential risk of shortening the service life of CFRP composite. The proposed research motives can result in development of specialist resin and/or isolating system to be used in situations where the coupled application of CP system and CFRP composites is needed.

The objectives of the project are:
a. To investigate the interaction between CP system and CFRP in RC structures with respect to the following parameters:
i. Extent of acid generation as a function of protection current density
ii. CFRP/concrete bond strength and its change with time
iii. Stray current corrosion of CFRP
iv. Type of adhesive
v. Structural performance of CFRP composites
b. To evaluate how the impact of CP on longevity of CFRP composite system can be minimised by altering the geometry of anodes, type of adhesive, method / sequence of application of CFRP and other additional protective measures.
