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...

Nederland is geen echt natuursteenland. Binnen de huidige grenzen wordt feitelijk alleen in de provincie Limburg natuursteen gewonnen voor toepassing in gebouwen: een zachte geelwitte kalksteen, in Nederland bekend als mergel, in België als Maastrichter steen. Wel werd altijd veel natuursteen van elders gehaald. Zeer bekend zijn de tufsteen uit...

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...

A microscopic survey of over 1000 of samples of concrete and masonry mortars from structures in the Netherlands shows that, in practice, self healing occurs in historic lime and lime – puzzolana mortars, in contrast to modern cement bound concretes and mortars. Self healing may be effected by the formation of either new Ca-carbonate, CaCO3, or...

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...

Opperulaktebehandelingen zoals steenverstevigen, hydrofoberen en antigraffiti bestaan al meer dan 100 jaar. Op het gebied van steenverstevigers wordt gebruik gemaakt van een reeks verschillende chemische producten, waarvan kiezelzure esters (ethylsilicaten zoals TEOS) thans de meest gangbare zijn (Nijland et al. 2009). Ze kennen echter hun...

Oppervlaktebehandelingen zijn beschermingsmaatregelen waarbij op of via het oppervlak van de gevel (veelal chemische) middelen worden aangebracht. Het doel van een oppervlaktebehandeling is schade te herstellen en/of het oppervlak van de materialen te beschermen tegen toekomstige aantasting. In dit hoofdstuk worden waterafstotende en...

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...

Delft is alom bekend van de Oude en de Nieuwe Kerk, beiden (deels) opgetrokken door bouwmeesters/ steenhouwers van het roemruchte Brabantse geslacht Keldermans en deels in de onvermijdelijk met deze bouwmeesters verbonden witte zandige kalksteen, meestal Lede of Balegemse steen genoemd. Met name aan de Oude Kerk is echter ook nogal wat...
