Influence of the carbon dioxide concentration on the resistance to carbonation of concrete

Visser, J.H.M. (author)

Carbonation of concrete at ambient CO2 concentration is a slow process. This makes the testing of the resistance of concrete against carbonation often too slow to be applicable for service life assessments of new structures. Raising the CO2-concentration will accelerate the test but the validity of an increase CO2 -level is debated. If not valid...

Evaluating the rheological properties of PMB-containing RA binders from surface-layer asphalt mixtures to be recycled

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 ...

Replacement of Eocene white sandy limestone in historical buildings: Over 100 years of practice in the Netherlands

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...

Interpreting structural damage in masonry: Diagnostic tool and approach

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...

Levensduurberekeningen voor betonconstructies

Visser, J.H.M. (author), Siemes, A.J.M. (author)

Steeds vaker wordt geëist dat betonconstructies zodanig worden ontworpen dat ze een gegarandeerde levensduur hebben. Het komt voor dat een levensduur van 100 of zelfs 200 jaar wordt geëist. Maar hoe ontwerp je een constructie met voldoende levensduur? Hoe bewijs de dan dat je aan die levensduureis voldoet? En waar moet je allemaal op letten als...

A mini-TSTM for measuring paste deformations at early ages

Koenders, E.A.B. (author), Schlangen, E. (author), Leegwater, G. (author), TNO Bouw en Ondergrond (author)

The start of the chemical reaction between cement and water is the moment that concrete starts to develop its properties. More precisely, it is the paste that starts to generate a loadbearing microstructure that exhibits a certain number of mechanical properties. One of the properties generated during hardening is the so-called hardening...

Modelling of autogenous shrinkage of concrete based on paste measurements

Schlangen, E. (author), Leegwater, G. (author), Koenders, E.A.B. (author), TNO Bouw en Ondergrond (author)

In order to be able to improve concrete modelling based on its constituent, more knowledge is needed about the material behaviour of these constituents. In this research the focus is on the behaviour of hardening concrete, therefore the properties of hardening cement are of most relevance. Information about cement paste behaviour can be used as...

Het juiste hout op de juiste plaats

De keuze voor de houtsoort van kozijnen wordt vaker bepaald door gewoonte dan door een bewuste afweging. Jammer, vindt FSC Nederland, want het assortiment van geschikte houtsoorten is enorm. De HoutScout adviseert aannemers welke houtsoort zij in een bepaald project het beste kunnen toepassen

Investigation on the performance of a restoration plaster in the field

Lubelli, B. (author), van Hees, R.P.J. (author), Groot, C.J.W.P. (author), TNO Bouw en Ondergrond (author)

The present paper reports the results of a series of investigalions carried out in a church located in the region of Zeeland, in the south-west part of the Netherlands. Because of the sea flooding occurred in 1953, this building shows a serious salt damage, mainly affecting the restoration plaster applied on the interior walls. This plaster,...
