Abstract

In the present project salt frost scaling was registered during an accelerated freeze-thaw test (CEN/TS 12390-9). After the test, inner damage was evaluated by observing the crack patterns on fluorescence impregnated plane sections. The results indicate that the developments of inner and outer damage are linked processes. The link is related to the moisture transport in the concrete, as both inner cracking and scaling change if a moisture barrier is implemented parallel to the test surface, 25 mm below the test surface.
