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

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
