Borsoi, G. (author), Van Hees, R. (author), Lubelli, B. (author), Veiga, R. (author), Santos Silva, A. (author)The development of nanomaterials is growing exponentially in the last decade. New discoveries and their applications have taken place in different fields, such as electronics, chemistry, biology and physics. Some innovative nanoproducts have become available also for the conservation of cultural heritage (e.g. nano-Ca(OH)2, nano-SiO2, nano-TiO2,...conference paper 2015

Van Hees, R.P.J. (author), Naldini, S. (author), Roos, J. (author)The section Heritage & Architecture of the Faculty of Architecture at Delft University of Technology deals with the built environment in terms of conservation, refurbishment and re-use. Reflecting the department philosophy, this book focuses on the durability and sustainability of existing buildings (heritage in a broad sense, from historic...book 2014

Van Hees, R.P.J. (author), Naldini, S. (author)Age and ageing can be felt as negative occurrences. For monuments however, old age is traditionally considered to be a positive quality. Without a certain age the nomination of monument hardly applies. Ageing can be seen as the work of time, which has always been valued: ageing was sometimes even artificially induced in the past. In this paper...conference paper 2014

Granneman, S.J.C. (author), Ruiz-Agudo, E. (author), Lubelli, B. (author), Van Hees, R.P.J. (author), Rodriguez-Navarro, C. (author)The use of crystallization modifiers for the prevention or mitigation of salt crystallization damage has recently received a lot of research interest in the field of building conservation. However, the use of crystallization modifiers mixed in a lime-based mortar, is still a very new field of research. This paper summarizes the literature study...conference paper 2014

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

Van Hees, R.P.J. (author)The usefulness of treatment of facades of historic buildings and especially those with the status of listed monument is often discussed. Surface treatments of facades comprise a range of treatments, from water repellents to consolidants and anti-graffiti coatings. Even facade cleaning can be considered a facade treatment. Treatment of monuments...conference paper 2013

Bolondi, L. (author), Nijland, T.G. (author), Van Hees, R.P.J. (author)Around the Tuscan city of Lucca, a complex system of about 300 villa has developed between 15th and 19th centuries in a ring of territory called the Six Miles District. Nowadays, many of the buildings inside the villas enclosures are damaged and their materials – in particular renders - need to be restored. A research program was developed...conference paper 2013

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. Salts present in porous materials cause damage through their interaction with moisture. Consequently, in certain situations the prevention of...conference paper 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

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

De Vent, I. (author), Rots, J.G. (author), Van Hees, R.P.J. (author), Hobbelman, G.J. (author)Cracks and deformatiçns in masonry are common phenomena in historical buildings. If they are interpreted correctly, they can be an extremely valuable source çf informatiçn on the load history of the premises. Nevertheless, this interpretation is not always as obvious as one may think. In the framework of a Phd research project, an extensive...conference paper 2012

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
