RILEM TC 277-LHS report
Properties of lime-based renders and plasters—discussion of current test methods and proposals for improvement
Renders and plasters have significant functions in buildings. Their functionality is closely related to their properties, which depend on the mortar itself, the application technology, the interaction with the environment and the substrate. There are many basic characteristics th

Recommendation of RILEM TC 271-ASC
New accelerated test procedure for the assessment of resistance of natural stone and fired-clay brick units against salt crystallization
This recommendation is devoted to testing the resistance of natural stone and fired-clay brick units against salt crystallization. The procedure was developed by the RILEM TC 271-ASC to evaluate the durability of porous building materials against salt crystallization through a la

RILEM TC 277-LHS report
Lime-based mortars for restoration–a review on long-term durability aspects and experience from practice
For conservation interventions of historic masonry generally lime-based mortars such as pure air lime mortars, lime-pozzolan mortars, natural hydraulic lime mortars and ternary mortars (lime-pozzolan-cement) are used. The main reason is that their hygric and mechanical (strength

Effectiveness of methods against rising damp in buildings
Results from the EMERISDA project
Rising damp is a recurrent hazard to ancient buildings in Europe and its relevance is expected to increase in the future, due to climate changes. The presence of rising damp in walls does not only create an unpleasant climate in buildings, but it also enhances damage processes su

RILEM TC 243-SGM report
Grouting for historic architectural surfaces
Historic Structures are commonly coated with mortar layers (plasters, renders, flooring) for protection and decoration. These well finished architectural stratigraphic surfaces often suffer from deterioration, such as lack of adhesion or detachment between support and mortar laye

The volcanic foundation of Dutch architecture
Use of Rhenish tuff and trass in the Netherlands in the past two millennia
Occasionally, a profound but distant connection between volcano and culture exists. This is the case between 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 c

Recommendation of RILEM TC 243-SGM
Functional requirements for surface repair mortars for historic buildings
Surface repair mortars are used for the compensation, or repair, of lost portions of surface materials in historic masonry buildings. It is recommended that their design and application should be performed in a wider context of conservation values related decision making, to prio

Restorative Glass
Reversible, discreet restoration using structural glass components
The application of structural glass as the principal material in restoration and conservation practices is a distinguishable, yet discreet approach. The transparency of glass allows the simultaneous perception of the monument at both its original and present condition, preserving

The durability of building materials with respect to salt crystallization is commonly determined by accelerated weathering tests, carried out in the laboratory. An effective laboratory weathering test should assess the durability and, in the case of conservation of historic build

Vochtschade na brand
De casus van de Elleboogkerk in Amersfoort
Het blussen van een brand gaat gepaard met een grote hoeveelheid water die in het metselwerk van een gebouw binnendringt; daarnaast duurt het vaak ook nog lange tijd voor een gebouw weer waterdicht kan worden gemaakt. Dit kan een hoog vochtgehalte in de muren veroorzaken, met all

Mitigating salt damage in building materials by the use of crystallization modifiers
A review and outlook
Salt crystallization damage in porous building materials is a widespread phenomenon. Several solutions to prevent, or mitigate, salt damage in building materials, prolonging thereby their service-life have been proposed. One of the latest approaches is the use of crystallization

Keuze van steenreparatiemortels voor historische gebouwen
Geen eenvoudige zaak
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 ontbre

Een plaag van alle tijden: zout
Over oude en toekomstige schade, oud en toekomstig onderzoek
In deze bijdrage wordt nader ingegaan op de achtergronden van zoutschade, de vraag of we er in de toekomst meer last van zullen krijgen, en op oud, nieuw en gewenst onderzoek.@en
Effect of solvent on nanolime transport within limestone
How to improve in-depth deposition
Consolidation treatment is a common practice in the field of conservation. However, when considering calcareous materials, there is a lack of efficient and durable consolidants. Colloidal dispersions of Ca(OH)2 nanoparticles, commonly known as nanolimes, can effectively recover t
