Fibres in Civil Engineering Structures

Start date 01/12/2012
End date The project is closed: 31/12/2017

​Corrosion is the most common cause of deterioration of reinforced concrete structures today. It negatively affects the safety of structures and causes high maintenance costs for society. The use of fibres could be beneficial in civil engineering structures, like bridges and harbour piers, where their crack limiting effects are of interest. However, the use of steel fibres in combination with traditional steel reinforcement raises questions regarding the influence of fibres on chloride ingress, the increased risk of corrosion due to a decreased electrolytic resistance, and the risk of galvanic corrosion.

This project consists of two parts. The first is an experimental investigation of the corrosion process in reinforced concrete beams with varying fibre reinforcement and load conditions. The second part involves computational modelling of the cracking process, the chloride ingress and the corrosion process. The purpose of the project is to understand how fibres influence the transport properties and the electrochemical corrosion process in reinforced cracked concrete structures, with respect to chloride induced reinforcement corrosion. The aim is to provide recommendations with respect to durability and input to service life models for fibre reinforced concrete structures, like tunnels and bridges.


The project is carried out at the Division of Structural Engineering, research group Concrete Structures.
