Abstract: Waterway structures like locks are exposed to severe freeze-thaw attack. Sufficient resistance of the concrete to this exposure has to be assured. In Germany the concrete used for federal waterway structures in exposure class XF3 has to undergo a CIF test in the laboratory in addition to meeting descriptive requirements. In the meantime, experience has been gained with this procedure and several structures based on it have been in operation for up to ten years. In order to establish the procedure, research was conducted concerning the transferability of laboratory tests to practical experience. One important aspect here was a service life study on the degree of water saturation of the concrete under practical conditions in combination with temperature exposure. Taking the example of a lock, this paper presents the results of laboratory tests as well as monitoring data for the degree of water saturation and temperature exposure and undertakes an assessment of the condition of the structural concrete after ten years in operation.
