Nijland, Timo G. (author), Lubelli, B. (author), van Zundert, Kim (author), van Hunen, Michiel (author)The impregnation of the exterior surface of a masonry wall with a water repellent is a common intervention in (historic) building renovation and maintenance. Such treatments, whilst degrading at the surface with time under influence of ultra violet light, remain effective below the surface several decades after their application. During...journal article 2024

Mulder, K.B. (author), Lubelli, B. (author), Dijkhuis, Edwin (author)Walls overgrown with plants can have a positive impact on urban comfort and contribute to biodiversity in the city. In particular, quay walls, thanks to their close contact with water, have the potential to be ecologically engineered to encourage the growth of herbaceous plants. Different factors can affect growth of vegetation on walls. This...journal article 2023

Lubelli, B. (author), des Bouvrie, Ernst (author), Nijland, Timo G. (author), Kamat, Ameya (author)Salt crystallization is a major cause of weathering of mortars, including plasters and renders. In the last decade, the use of mixed-in salt crystallization inhibitors in mortars has been proposed as a solution to improve the durability of this material with respect to salt decay. Laboratory characterization and accelerated weathering tests have...journal article 2023

Tunable chitosan-alginate capsules for a controlled release of crystallisation inhibitors in mortarsKamat, Ameya (author), Palin, D. (author), Lubelli, B. (author), Schlangen, E. (author)Plasters and renders used in historic monuments are vulnerable to degradation caused by salt weathering. Crystallisation inhibitors (molecules/ions that alter salt crystallisation) mixed into mortars have shown promising results in mitigating salt damage by inhibiting salt crystallisation, promoting salt transport to the evaporating surface, and...conference paper 2023

Kamat, Ameya (author), Lubelli, B. (author), Schlangen, E. (author)Crystallisation due to commonly occurring salts like sodium chloride (NaCl) is a known cause of damage in the built environment. Use of crystallisation inhibitors is a potential solution to reduce salt decay in building materials. Researchers have reported lower damage when sodium ferrocyanide (NaFeCN), a known NaCl crystallisation inhibitor, is...abstract 2023

Lubelli, B. (author)Salt weathering is one of the most recurrent damage processes affecting both the natural and the built environment. Due to the complexity of the process, numerical models are rarely applied in practice; accelerated weathering tests in laboratory are still the most common way to assess and forecast durability of (conservation and renovation)...abstract 2023

Kamat, Ameya (author), Lubelli, B. (author), Schlangen, E. (author)This paper investigates the leaching behaviour of sodium ferrocyanide, a known crystallisation inhibitor of sodium chloride, which is added to mortars for mitigation of salt decay. Leaching and depletion of the inhibitor is a practical performance related issue that might over time, make the inhibitor less effective against salt decay. In...journal article 2023

Kamat, Ameya (author), Lubelli, B. (author), Schlangen, E. (author)Sodium chloride (NaCl) is one of the most commonly occurring weathering agents, responsible for a progressive damage in mortar. Current solutions to mitigate salt damage in mortar, such as the use of mixed-in water repellent additives, have often exhibited low compatibility with the existing building fabric. In the last years, research has...book chapter 2023
