Abstract

The microenvironment existing at the surface of a concrete element which has shown rapid deterioration in the form of scaling has been established. Field measurements of the microclimatic elements within the concrete surface layer throughout the winter give new insight into the understanding of the surface scaling. It was found that solar effects have a pronounced effect on the scaling of the concrete surface. Basis for a new scaling test which simulates the deterioration of concrete in the field under severe freeze-thaw conditions has been developed. It consists of partial thawing and complete refreezing of the surface. Erratum to this paper appears in 11(1).
