The role of porosity on degradation of concrete under severe internal and external brine attack in confined conditions

It has been observed that a trench wall embedded in the soil of the Dead Sea has lost strength and is deteriorating due to brine attack. This phenomenon demonstrates that concrete wall structural stability and durability can be seriously endangered. Yet conventional analysis using macroscopic models is considered an oversimplification, as it...

Durability of an UHPFRC under mechanical and chloride loads

The high cost of UHPFRC is a limitation on the practical application in real construction projects. However, a very competitive UHPFRC approach is the hybrid structural elements, where thin layers of UHPFRC are employed to rehabilitate/strengthen damage cover concrete. New layers subjected to harsh conditions (loads and/or environmental) can...
