Non-saturated Chloride Diffusion in Sustainable Cementitious Materials

Chloride-induced reinforcement corrosion, caused by chloride diffusion in the unsaturated concrete cover, is a major durability problem of concrete structures. Current concepts for concrete mixture design and for service life prediction are generally based on the understanding of the chloride diffusion coefficient of saturated concrete. This...

Deflections and Natural Frequencies as Parameters for Structural Health Monitoring: The Effect of Fatigue and Corrosion on the Deflections and the Natural Frequencies of Reinforced Concrete Beams

The Dutch road infrastructure contains a large number of concrete bridges and viaducts. Malfunction of these bridges and viaducts has large financial consequences. To avoid malfunctions of bridges, bridges need to be inspected frequently and actions should be taken when required. The reliability of the inspections of the health of a bridge could...
