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,...

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 ...

Steenreparatiemortels worden gebruikt voor het aanvullen van een ontbrekend deel van het originele materiaal. Dat laatste kan verloren zijn gegaan door een mechanische belasting of door bijvoorbeeld aantastingsprocessen waarbij vocht, vorst en of zouten een rol spelen. Het ontbrekende deel wordt dan aangevuld met een mortel met een passende...

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,...

Surface treatments are all those products that are applied on the surface of buildings with the most different aims. Water repellents, consolidants and antigraffiti coatings belong to this category. In this paper the focus will be on water

Although salt crystallization damage is a widespread damage process in the porous materials of our built cultural heritage, no definite solution yet exists to improve the durability of materials with respect to salt crystallization. Most research focuses on improving material properties, whereas only few studies concentrate on changing the...

Oppervlaktebehandelingen zijn beschermingsmaatregelen waarbij op of via het oppervlak van de gevel middelen worden aangebracht. Er zijn verschillende vormen van oppervlaktebehandeling. In deze bijdrage worden alleen waterafstotende en steenverstevigende behandelingen besproken

Salt crystallization is one of the most common causes of decay of porous building materials. Salts can cause damage when they, due to the presence of moisture, undergo crystallization/dissolution cycles. Removing the moisture source can

The quality of the materials constituting masonry has a major influence on the type and seriousness of the damage that can occur due to salt crystallization. In the case of brick, the composition of the original clay, together with the production process, determine the quality of the final product and it's eventual susceptibility to salt decay....

Sea salt damage to porous building materials is a well-known problem not only in regions located near the sea, but also in continental areas. In walls sea salts may stem from different sources: they may penetrate from the ground by rising damp, may be carried by the wind in the form of salt spray, may be due to flooding, occasional or recurrent,...

For the understanding of the salt crystallisation mechanism in restoration plasters, the understanding of water (moisture) transport is essential, as it is the influence of salts on the water transport. More specifically the drying behaviour, i.e. the moisture / salt transport and distribution during the drying, is important.
