Abstract

Modelling of frost damage is a key element in the life cycle management of concrete structures. In case of a pure freeze-thaw cyclic loading, a depth-resolved quantification of the water saturation behaviour of concrete is of key interest, as the concrete damage is directly linked to the saturation behaviour and as every freeze-thaw cycle provokes an increase of the degree of saturation. Upon reaching a critical value of saturation structural damage will occur at only one freeze-thaw cycle. The frost suction cannot be described from single classical transport laws. So the challenge in assessing the saturation behaviour of concrete is a continuous, non-destructive and spatially resolved registration of the water uptake during the frost exposure. Based on time- and depth-resolved experimental moisture investigations during the freezing-thawing action on hardened cement paste a new engineering model approach was developed.
