The elastic modulus of corrosion product (Ecp) has been reported with significant variations in the literature. This study aims to investigate the Ecp of naturally-generated chloride-induced corrosion products formed in different concrete mixes. Microstructural characterization was conducted through nano-indentation, electron microscopy and...

An important input parameter for numerical models that simulate cracking of the concrete cover due to reinforcement corrosion is the Elastic modulus of corrosion product (Ecp). Despite its relevance, Ecp is subject of significant variations according to the values reported in the literature, which vary from less than 100 MPa up to 360 GPa....

The durability design of reinforced concrete structures has been recently included in the main national and international design codes, and it is aimed at corrosion prevention of steel reinforcement during the designed service life. Therefore, since the design stage, it is of fundamental importance to correctly assess the temporal evolution of...

Although reinforcement corrosion is a well-known issue, which are the locations of the steel/concrete interface most sensitive to pitting corrosion is still an unclear issue. In this study, X-ray computed tomography is used to characterize eight 20-years-old reinforced concrete cores naturally deteriorated due to chloride-induced corrosion. The...

Service life of reinforced concrete structures is usually limited to initiation of corrosion, whilst in practice corrosion in many structures is already in the propagation stage. To better understand the processes that leads to the cracking and detachment of concrete cover during this phase, the knowledge of corrosion products development in...

Although corrosion of reinforcement is a well-known issue for the construction industry, there are still open questions about some fundamentals of corrosion in reinforced concrete. These points include, among others, which are the most sensitive locations of the steel/concrete interface for pitting corrosion to initiate and to propagate. In this...
