Yang, Z. (author), Fischer, H.R. (author), Cerezo, J. (author), Mol, J.M.C. (author), Polder, R.B. (author)A carbonate form of MgAl hydrotalcite, Mg(2)Al-CO3 and its p-aminobenzoate (pAB) modified derivative, Mg(2)Al-pAB, were synthesized and characterized by means of XRD, FT-IR and TG/DSC. The anticorrosion behavior of Mg(2)Al-pAB was evaluated based on open circuit potential (OCP) of carbon steel in simulated concrete pore solution and on chloride...article 2013

Polder, R.B. (author), Peelen, W.H.A. (author), Raupach, M. (author), Reichling, K. (author)This paper investigates the economic effects of full corrosion surveys of concrete structures. The background is that the existing concrete infrastructure is aging, while being exposed to aggressive influences, which increases the occurrence of corrosion and related concrete damage over time. The central proposition is that solely relying on...article 2013

Yang, Z. (author), Fischer, H.R. (author), Polder, R.B. (author)Modified hydrotalcites (MTHs) represent a group of technologically promising materials for addition to concrete to improve its durability in aggressive environment, owing to their low cost, relative simplicity of preparation, and plenty of unique composition variables that may be adopted. Up to date, a lot of academic work and commercial...article 2013

Lubelli, B.A. (author), van Hees, R.P.J. (author), Hacquebord, A. (author)Injection of chemicals in masonry walls is a commonly used technique for tackling rising damp. The presence of a high moisture content in the wall to be injected may sometimes limit the effectiveness of the intervention. This paper reports an experimental study of curing time, spreading and effectiveness of 15 injection products in bricks with...article 2013

Liu, G. (author), Leegwater, G. (author), Nielsen, E. (author), Komacka, J. (author), Ven, M.V.D. (author)A rapidly increasing source of reclaimed asphalt (RA) that contains polymer modified bitumen (PMB) offers a potential premium material contribution when performing recycling. This study investigated the rheological properties of three PMB-containing RA binders from different "old" surface-layer asphalt mixtures in Europe and their impacts on ...article 2013

Quist, W.J. (author), Nijland, T.G. (author), van Hees, R.P.J. (author)This paper discusses the replacement of white sandy limestone (Gobertange and Lede or Balegem) in the Netherlands in (successive) restorations from the mid-19th century onwards. White sandy limestone, transported from the southern part of the Low Countries (now Belgium), was extensively used in the northwestern part of the present-day...article 2013

de Vent, A.E. (author), Rots, J.G. (author), van Hees, R.P.J. (author)A sound diagnosis can only be reached starting from a correct interpretation of the damage. This is not always an easy task: symptoms may be misunderstood, alternative hypotheses overlooked, and the context of the damage left unconsidered. This paper aims to offer architects, contractors and engineers a helping hand in interpreting structural...article 2013

Nijland, T.G. (author), Touret, J.L.R. (author)Abstract Granulites constitute a major part of the (lower) continental crust, occurring on a regional scale in many metamorphic belts. Their origin is generally discussed in terms of vapour-absent melting and fluid-assisted dehydration. This last model is notably supported by the occurrence of two immiscible free fluids at peak- and retrograde...bookPart 2012

Pacheco, J. (author), Polder, R.B. (author), Fraaij, A.L.A. (author), Mol, J.M.C. (author)Cathodic Protection (CP) of steel in concrete has been used over the past decades in order to increase the remaining service life of concrete infrastructure. CP involves the application of an electrical current to the corroding reinforcing bars, thus stopping and preventing further corrosion. The application of current on the reinforcing steel...conference paper 2012

(author)Steel is discarded by railway owners as a material for underground structures near railway lines, due to uncertainty over increased corrosion by DC stray currents stemming from the traction power system. This paper presents a large scale field test in which stray currents interference of a sheet pile wall was monitored in realistic conditions....conference paper 2012
