Reliability of Porous Materials: Two Stochastic Approaches

The first decay shown by masonry subjected to an aggressive environment is the loss of surface material. The great randomness of this kind of decay phenomenon suggests studying it from a probabilistic point of view. Here, the evolution of decay in stone masonry has been investigated by applying two different approaches on experimental data collected on on-site models. Since the results are very similar, the choice of approach depends only on the available data and the monitoring time.
