Ruiz-Agudo, E. (author), Lubelli, B. (author), Sawdy, A. (author), Van Hees, R. (author), Price, C. (author), Rodriguez-Navarro, C. (author)San Jeronimo Monastery (Granada, Spain) was selected as a case study for the investigation of the effect of indoor environmental conditions on salt weathering and for on-site testing of a remediation treatment using crystallization inhibitors on account of the extreme salt damage affecting both the building stone, a biomicritic limestone,...journal article 2010

Van Hees, R.P.J. (author), Lubelli, B. (author)Salt crystallization constitutes one of the most widespread decay mechanisms affecting historic buildings. Desalination is a conservation treatment of growing importance in the case of historic masonry. This paper describes the approach from pre-investigation and treatment to follow-up care as the basis for a successful preventive conservation...journal article 2010

Lubelli, B. (author), Nijland, T.G. (author), Van Hees, R.P.J. (author)Lime mortars have, up to a certain extent, a self-healing capacity which may contribute to their durability. Self-healing in lime mortars consists of a process of dissolution, transport and re-precipitation of calcium compounds to heal cracks and fissures. The spontaneous occurrence of self-healing in lime-based mortars is a well known...journal article 2011

Lubelli, B. (author), Nijland, T.G. (author), Van Hees, R.P.J. (author)In the present research a test procedure was set up to reproduce self-healing on lime-based (both pure calcium and magnesium-calcium) mortar specimens in laboratory. After few months testing, during which the specimens were subjected to wet-dry cycles, thin sections of the specimens were prepared and observed by Polarization and Fluorescence...conference paper 2011

Van Hees, R.P.J. (author), Lubelli, B. (author)Zoutkristallisatie kan leiden tot ernstige aantasting van steen en metselwerlk. Dit veelvoorkomende probleem vormt bij de zorg voor monumenten een blijvend punt van aandacht. In dit artikel wordt beschreven hoe het mechanisme van zoutkristallisatie werlct en ook op welke manieren zoutkristallisatie zich manifesteert. Het grote aantal factoren...book chapter 2011

Van Hees, R.P.J. (author), Lubelli, B. (author)Zoutkristallisatie is een van de meest voorkomende bedreigingen voor historische gebouwen. Zouten, aanwezig in poreuze materialen kunnen in interactie met vocht schade veroorzaken. Omdat vocht essentieel is voor dit schadeproces, kan onder sommige omstandigheden een ingreep, die verdere vochttoetreding tegengaat, een oplossing voor het probleem...conference paper 2012

Hacquebord, A. (author), Lubelli, B. (author), Van Hees, R.P.J. (author)Metselwerk kan zwaar te lijden hebben onder verschillende degradatieprocessen. Bij veel van deze degradatieprocessen speelt vocht een grote rol. Eén van de belangrijkste en tegelijk vaak moeilijk te bestrijden vochtbronnen voor metselwerk is optrekkend vocht. Men spreekt van optrekkend vocht als water vanuit het grondpakket via de capillairen...conference paper 2012

Lubelli, B. (author), Van Hees, R.P.J. (author)Ontzouten door het gebruik van kompressen is een techniek die meer en meer gebruikt wordt in de conservering van historisch metselwerk. Niettemin, wordt ontzouten nog vaak uitgevoerd op een trial and error basis, zonder wetenschappelijke kennis van de processen die vocht- en zouttransport regelen. Om het ontzoutingsproces te optimaliseren is,...conference paper 2012

Hacquebord, A. (author), Lubelli, B. (author), Van Hees, R.P.J. (author), Nijland, T. (author)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...journal article 2013

Lubelli, B. (author)Salt crystallization damage is one of the most common causes of decay for bedding, pointing and plastering mortar. Attempts to tackle the problem have been mainly focused on increasing the mechanical strength of the mortar, by the replacement of lime with (PTL) cement, or on reducing the moisture transport capacity, by the addition of silicone...lecture notes 2013

Granneman, S.J.C. (author), Lubelli, B. (author), Van Hees, R.P.J. (author)The weathering of porous materials due to the presence of salts has been known since antiquity. However, serious studies and investigations were not conducted until the 19th century. One of the fi elds of interest includes historic masonry, where salt damage can affect natural stone, brick and mortar (see Figure 1). Mortars are building...journal article 2013

Lubelli, B. (author), Van Hees, R.P.J. (author), Nijland, T.G. (author)Salt crystallization is a major cause of damage in porous building materials. Notwithstanding the extensive research in this field, the complexity of the problem has hindered the use of mathematical models for forecasting ageing and damage due to salt crystallization. Nowadays, the durability of materials with respect to salt crystallization is...conference paper 2014
