Abstract

The conditions of historical brickwork in Venice are very peculiar indeed because the presence of seawater influences, directly or indirectly, the wall systems. We have initiated a study concerning the physical and chemical effects of water on the brick walls along the canals, which are usually submerged during the sea high tide. The situation examined is the worst one, since both the cyclic contact of brickwork with water and the physical effect of wave movements occur concurrently. Chemical analyses and porosity measurements have been performed on samples taken from walls of different age and exposed differently to the tidal waters. Tests have been performed on, the samples at various depths, in order to evaluate the changes in the parameters and to define the relationships among the physical and chemical processes leading to the decay of the material. © 1994 RILEM.
