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,...

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 ...

tThe application of new consolidating products on the surface of weathered materials is a common inter-vention technique in conservation practice. Due to the difficulty of producing artificially weatheredsubstrates in a reproducible way, the effect of consolidating products in laboratory is generally assessedon sound substrates. However, the...

Rising damp is one of the most recurrent and well-known hazards to existing buildings and monuments. Several types of intervention exist to tackle the problem. Among these, the creation of a damp-proof course against capillary rise by means of injection of chemical products is one of the most diffused methods, thanks to the relatively easy and...

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...

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...
