Salt crystallization damage: how realistic are existing ageing tests?
conference paper
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 mostly determined by accelerated
ageing tests, carried out in laboratory following different test procedures. An effective ageing test
should simulate in laboratory, in a reliable way and within a relatively short period of time, the
behaviour in practice. The question is whether existing test procedures are able to do so. This paper
reports a critical overview of existing procedures and suggests directions for further research.
