Study on effective modifiers for damaging salts in mortar
conference paper
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 aimed at the identification of a possible modifier for
sodium sulfate, one of the most damaging salts found in porous building materials. Furthermore, the
results of preliminary experiments conducted in order to test the suitability of borax as a crystallization
modifier for sodium sulfate are reported and discussed.
