The cloister of Santa Maria (Segovia, Spain) is mainly bui/t of dolomicrite and dolomitized pelmicrite. After exposure to similar environmental conditions, there are distinctive indicators, namely alveolar decay of pelmicrites, of the alteration of these materials. The development of pathological features in pelmicrites is due to the combination of intrinsic factors, specially texture, and the chemical action of water. The hydric behaviour of pelmicrites, their specific surface, their low contact angle with water and the wind action, favour moisture-dryness processes causing typical alveolar pathology.
