Assessment of salt damage is important for the conservation of brick structures. Some earlier findings on salt crystallization characteristics, crystallization pressures and durability expressions have been reviewed for this purpose. In the experimental part of this work, salt damage has been examined by scanning electron microscopy, by water and water vapour sorption measurements and by mercury porosimetry before and after artificial salt crystallization tests. Change in pore structure, considerable increase in the percentage of finer pores, some increase in total porosity, spontaneous water absorption and water vapour sorption is noted. Decrease in durability has been calculated by using MAAGE’S equation.
