Abstract: Chloride ingress is one of the main causes of corrosion of the reinforcement in concrete structures, certainly for structures that are highly exposed to chlorides, such as off-shore or on-shore constructions in marine environment. This paper deals with the quay-wall of the new container terminal at Zeebrugge Harbor, Belgium, which is protected against chloride ingress by means of a water repellent agent immediately after construction in 1993 using an alkyltriethoxysilane, pre-evaluated in a preliminary research program. To judge the in site effectiveness of the hydrophobic agent as a water repellent treatment, three subsequent in site surveys have been conducted in 1996, 1998 and recently in 2005. Based on the cores drilled, the chloride profiles are determined as a function of time, both in a non-treated and treated location. The results are presented and discussed. Because of the long-term data sequence, the long-term effectiveness of the treatment can be assessed in an objective way. (c) 2006 Elsevier Ltd. All rights reserved.
