An important input parameter for numerical models that simulate cracking of the concrete cover due to reinforcement corrosion is the Elastic modulus of corrosion product (Ecp). Despite its relevance, Ecp is subject of significant variations according to the values reported in the literature, which vary from less than 100 MPa up to 360 GPa....

In the Netherlands, beside cement replacement with more green cement types, there is also an urgent need for alternative materials for natural sand in new concrete in order to make it circular. Furthermore, the recyclers have raised questions regarding upscaling and the potential of fine recycled concrete aggregates (fRCA) in structural concrete...

The durability design of reinforced concrete structures has been recently included in the main national and international design codes, and it is aimed at corrosion prevention of steel reinforcement during the designed service life. Therefore, since the design stage, it is of fundamental importance to correctly assess the temporal evolution of...

De Obernkirchener zandsteen, in oude bouwrekeningen vaak als Bremer steen aangeduid, is afkomstig van de Bückeberge tussen Minden (Westfalen) en Hannover. De zandsteen is afgezet in het Onder-Krijt (Berriasiaan) en leent zich goed voor fijn geprofileerd werk. De steen wordt sinds de 11e eeuw gebruikt in de eigen regio. Getransporteerd over de...

Commercial, ready mix stone repair mortars have often been applied in conservation practice for the restoration of natura! stone, brick and terracotta, over the last decades with varying success in terms of durability of the repair mortar itself and compatibility with the substrate. In this research, four commercial stone repair mortars,...

Although corrosion of reinforcement is a well-known issue for the construction industry, there are still open questions about some fundamentals of corrosion in reinforced concrete. These points include, among others, which are the most sensitive locations of the steel/concrete interface for pitting corrosion to initiate and to propagate. In this...

Steenreparatiemortels zijn mortels die in de conserveringspraktijk worden gebruikt om ontbrekende delen van baksteen of natuursteen in metselwerk of beeldhouwwerk aan te vullen. In de Nederlandse conserveringspraktijk worden steenreparatiemortels regelmatig gebruikt met wisselende resultaten, zowel qua compatibiliteit met het bestaande als qua ...

Volcanic tuffstone from the Eifel region, Germany, is one of the most important kinds of natural stone used in the Netherlands. These tuffs have, albeit with several hiatuses, been used since Roman times. At several places, original Medieval stones are still present. That does not imply that the stone is completely resistant to weathering: ' The...

De Noordersluis bij IJmuiden is één van de grote infrastructurele werken in vooroorlogs Nederland, uitgevoerd in beton (Fig. 1). De bouw van de nieuwe sluis was onderdeel van een reeks verbeteringen aan het Noordzeekanaal: In 1909 was een staatscommissie ingesteld '(om)dat opnieuw de vraag rees of de belangen van Nederland in het algemeen en van...

Occasionally, a profound but distant connection between volcanos and culture exists. This is the case for the volcanic Eifel region in Germany and historic construction in the Netherlands, with the river Rhine as physical and enabling connection. Volcanic tuff from the Eifel comprises a significant amount of the building mass in Dutch built...

Recently TNO has established EBL2; an exposure and analysis facility for testing EUV optics, reticles and pellicles under relevant EUV scanner and source conditions. The facility and EUV source complies with the ASML power roadmap of EUV systems up to a power of 500 W IF. This enables life time testing of EUV optics, reticles and pellicles under...

Tuffstone elements with a large length/width ratio, as e.g. mullions, often suffer damage in the form of cracks parallel to the surface and spalling of the outer layer. The response of tuff to moisture might be a reason for this behaviour. This research aimed at verifying if a differential dilation between parts with different moisture content ...

TNO is building EBL2 as a publicly accessible test facility for EUV lithography related development of photomasks, pellicles, optics, and other components requiring EUV exposure. EBL2 consists of a EUV Beam Line, a XPS system, and sample handling infrastructure. Recently we finished installation of the source, exposure chamber, handlers and XPS...

Soms is de geschiedenis wonderlijk. Zo loopt er een directe lijn van de Frans-Duitse oorlog van 1870-1871 naar de Nederlandse restauratiepraktijk. Frankrijk verloor Elzas-Lotharingen aan het verenigde Duitsland. Talrijke Fransen ontvluchtten al tijdens de oorlog de verloren gegane gebieden, waaronder Jacques-Louis Kessler. Kessler vluchtte in...

TNO is building EBL2: a laboratory EUV exposure system capable of operating at high broad band EUV powers and intensities, in which XPS analysis of exposed samples is possible without breaking vacuum. Its goal is to accelerate the development and testing of EUV optics and components by providing a publicly accessible exposure and analysis...

Vanaf de Romeinse tijd tot in de 19e eeuw is historisch metselwerk in monumenten en ander gebouwd erfgoed vaak vervaardigd met kalk- of kalk-puzzolaanmortels. Sommige kalken zijn van nature in meer of mindere mate hydraulisch. In de 19e eeuw begint wetenschappelijk onderzoek naar hydraulisch bindmiddelen en doen natuurlijke hydraulisch kalk,...
