Abstract

This report deals with dynamic processes of polymers often used as paints coatings and finishes in housing, and also refers to their influence as the reduction in protective performance on the durability of reinforced concrete. The deterioration process of polymers by the simultaneous action of ultraviolet (UV) light and diffusive oxygen is explained theoretically based upon unsteady state dynamics. The parabolic law is derived for a typical path for the progress of the deteriorated layer of polymers inwards from the surface, and compared with some experimental data. The same parabolic law involving constant term was also derived for the carbonation of concrete, which well explains the retardation effects of finishes on the carbonation.
