Damage mechanisms and decay patterns on brick masonry due to sea salts
conference paper
Sea salt damage to porous buitding materials is a well-known problem not only in regions located near the sea, but
even in continental areas. Dffirent decay patterns qre observedfor different moisture and sea solt origins and dffirent
enyironmentql conditions. Besides, decay due lo sea sahs (mainly sodium chloride) is orten not only due to pure
cryslallization but also to the fficl lhat these salts can have on other damaging mechanisms, enhancing some chemÃcal
reaclions. In this paper the case of a building, where vqrious sources of sea sahs qre present in the same masonry wall,
is illuslrated.
