Peelen, W.H.A. (author), Visser, J.H.M. (author), Polder, R.B. (author), TNO Bouw en Ondergrond (author)In prefab segmenten van de Groene Harttunnel zijn sensoren ingebouwd voor het monitoren van aspecten van de levensduur. Corrosie-indicatie en elektrische weerstand worden gemeten. Ondersteund doorr laboratoriumproeven worden het vochtprofiel aan de binnen- en buitenkant van de tunnel daaruit afgeleid en het corrosiemechanisme (onder meer...article 2006

TNO Bouw en Ondergrond (author), Polder, R.B. (author), de Rooij, M.R. (author)This article presents a series of investigations on six concrete structures along the North Sea coast in The Netherlands. They had ages between 18 and 41 years and most of them were made using Blast Furnace Slag cement. Visual inspections showed corrosion damage in only one structure, related to relatively low cover depths. All structures showed...article 2006

Peelen, W.H.A. (author), Polder, R.B. (author), TNO Bouw (author)Assessment of the durability of prestressed concrete sheet piles under the interference of CP gas pipeline system current, established that due to their low magnitude, these currents do not compromise the required 100-year service life of the structures. The sophisticated numerical modelling tools being developed, are important in assessing...article 2004

Peelen, W.H.A. (author), Polder, R.B. (author), TNO Bouw (author)The new Dutch railway line the 'Betuweroute' crosses the main gas pipeline system of the 'Gasunie', the main Dutch gas distributor, at 7 locations. To ensure a safe operation of both the railway line and the pipeline system, it is essential to guarantee the mechanical stability of the gas pipes in the soft soil; therefore at several locations...conference paper 2004

Gaal, G.C.M. (author), Polder, R.B. (author), Walraven, J.C. (author), van der Veen, C. (author), TNO Bouw (author)Deterioration of concrete structures has become an important issue over the last decade. The most fre-quently observed form of deterioration is chloride-initiated corrosion of the reinforcement. Corrosion is initiated when the chloride content at the reinforcement exceeds the critical or threshold chloride content. However the threshold values...conference paper 2003

Polder, R.B. (author), Peelen, W.H.A. (author), TNO Bouw (author)This paper describes the effects of stray currents on durability and reinforcement corrosion of underground concrete structures. Cathodic protection of underground pipelines are stationary sources of stray current interference with concrete, and rail traction systems are non-stationary sources. The soil is the electrolyte that conducts stray...conference paper 2003

Schuten, G. (author), Leggedoor, J. (author), Polder, R.B. (author), Peelen, W.H.A. (author), TNO Bouw (author)The first system for Cathodic Protection of concrete in the Netherlands was applied to a one bicycle lane of a bridge suffering corrosion due to de-icing salt penetration in 1986. This CP system was based on the Ferex 100S conducting polymer cable anode in a cementitious overlay. Its functioning was investigated in 1998, which showed that some...article 2003
