Concrete is a poor conductor of heat. Nevertheless, heating of concrete results in physico-chemical conditions shifting in or out the thermodynamic stability field of specific phases (minerals) in the concrete, effectuating their (dis)appearance. Metamorphic petrology is a branch of geology that deals with the study of such changes; as a basic...

Van alle processen die schade aan beton veroorzaken is wapeningscorrosie veruit de belangrijkste. Daarnaast zijn z.g. alkali - aggregaat reacties (AAR) een belangrijke oorzaak van de aantasting van betonconstructies. Alkali - aggregaat reacties zijn chemische reacties tussen alkaliën (natrium, Na, en kalium, K) in het beton en bepaalde reactieve...

Een van de meest interessante gesteenten in Nederland, als we hat Nederlands-Duitse grensgebied daar veer hat gemak even bij nemen, is de Bentheimer zandsteen. Dit unieke gesteente onderscheidt zich doordat hat in ens land sinds vela eeuwen op grate schaal is toegepast als bouwsteen, terwijl hat oak een belangrijk oliereservoirgesteente is. Dit...

De CUR heeft recent de Nederlandse regelgeving herzien ter preventie van betonschade door alkali-silicareactie (ASR). In dit artikel wordt een beknopt overzicht gegeven van deze nieuwe regelgeving, de CUR-Aanbeveling 89. De aanbeveling is gemaakt voor de Nederlandse praktijk. Er is voor geko-zende de kans op het optreden van schadelijke ASR te...

In 1992, the first structure with deleterious ASR was diagnosed in the Netherlands, followed by the publication of the first Dutch guideline on the prevention of ASR in 1994. Since, ASR has been demonstrated in 40 to 50 structures over the country. Development of ASR in a series of structures on a major Dutch motorway, built in the late sixties ...

Black weathering of sandstone in monuments is widespread. Some obiects owe their name to it, like the Porta Nigra in Triet (Germany). Other than the black gypsum crusts common on limestone, the black weathering layer on sandstone is rather thin and well adhe¡ent. Formation of such layers on Bentheim and Obernkirchen sandstone, both widely used...

Rhenish tuffs from the volcanic Eifel region, Germany, have widely been used as building stone in the Netherlands. Different kinds of tuff (Römer, Weiberner, Ettringer, Riedener) show different kinds of decay, and also within each group, remarkable differences in weathering behaviour occur. In the present study, a short introduction is given to...

Especially in the western part of the Netherlands, Eocene sandy limestones from Belgium have elaborately been used in the construction of many 13th – 17th century monuments. These comprise both the Lede or Balegem stone from the Lede formation and the Gobertange stone from the Brussels formation. Over the centuries, both stones suffered serious...

Rhenish tuffs (Rmer, Weiberner / Hohenleie, Et-tringer / Hasenstoppler) from the volcanic Eifel re-gion, Germany, have widely been used as building stone in the Netherlands. In the present paper, an overview is given of their historic use in the Nether-lands, the experience with weathering, the search of good replacement stones for the Riimer...

Rhenish tuffs from the volcanic Eifel region, Germany, are amongst the most prominent and voluminous natural stones in Dutch monuments. In particular, tuffs from the 11,900 bp Laacher See eruption have been used since Roman times, - hence the name Römer tuff-, and were widely used again in romanesque (and to lesser extent romanogothic and early...

A test procedure was set up to reproduce laboratory self-healing on lime-based (both pure calcium and magnesium-calcium) mortar specimens. After a few months of testing, during which time the specimens were submitted to wet-dry cycles, thin sections of the specimens were prepared and observed using a polarization and fluorescence microscope (PFM...

Before the general acceptance of Portland cement as the main binder for concrete in the late 19th century, other, locally available binders were occasionally used. In the case of the Netherlands, which did not produce Portland cement, traditional lime-based binders were not uncommon. With a strong tradition of trass production, trass-lime...
