Rising damp removal from historical masonries: A still open challenge

“…e influence of these deterioration processes depends on the topoclimatic environmental conditions, the material type, its preservation state, and location on the building [3,4]. e circulation of water within microstructures of porous materials causes them to deteriorate considerably more rapidly, consequently compromising their behaviour [5][6][7].…”

An intermingled fractal units' model is shown in order to simulate pore microstructures as pore fraction and pore size distribution. is model is aimed at predicting capillary water absorption coefficient and sorptivity values in cement pastes. e results obtained are in good agreement with the experimental ones. For validating this model, a comparison with other procedures has been shown. It is possible to establish that the newly proposed method matches better with the experimental results. at is probably due to the fact that pore size distribution has been considered as a whole. Moreover, even though the proposed model is based on fractal base units, it is able to simulate and predict different properties as well as nonfractal porous microstructure.

“…Soaked masonries often show serious conservation issues. The phenomenon and the resulting decay have been extensively studied [1][2][3][4], as well as possible remediation methods [5,6], both from the theoretical point of view [7][8][9][10][11], and on several real case studies all over the world [2,[12][13][14][15][16][17].…”

A B S T R A C TConsidering several real case studies, moisture distribution due to rising damp in Venetian brick masonries is discussed and empirical models are developed. Moisture content and soluble salt data of 25 historical buildings in Venice are analysed. Data are scrutinized using statistical methods, obtaining contour plots and estimating the validity of linear and non-linear models. The models confirm that masonries are usually soaked with water till 120-150 cm over sea level, while the evaporation zone ranges in height from 200 cm to 350 cm. In the perpendicular section, moisture distribution depends on several contingent factors such as, among them, the proximity and the exposition of the external façades to the water action.
