Project - Danish Expert Centre for Infrastructure constructions

Project period: July 2010 - December 2012.

The centre is based on a close cooperation between the Concrete Centre at Danish Technological Institute and the Department of Civil Engineering at the Technical University of Denmark.  The aim is to combine and utilize complementary competences and laboratory facilities.

Goals for the project
The research topics of the expert centre include:

  • Seawater affected concrete structure’s long-term durability
  • Models for chloride binding
  • The influence of casting defects as well as unavoidable structural weaknesses on long-term durability
  • Influence of rheology and casting method on durability of structures cast with SCC
  • The influence of micro defects on durability
  • Chloride threshold values for initiation of corrosion and corrosion rates in the propagation phase. Influence of binder system and environmental conditions.
  • Models for cracks, including understanding damage formation in and through the interface between reinforcement and concrete.
  • Numerical service life models based on chloride driven reinforcement corrosion and later expanded to other degradation mechanisms.

Participants
A number of external cooperation partners are related to the expert centre with an advisory role.

The expert centre is co-financed by the Danish Ministry of Science, Technology and Innovation.
