Marble thin panels are widely used for external building envelope application, due to their original light transparency effects during day-time and night-time. Considering their application in polluted environments and the interaction with aggressive agents, the aesthetical characteristics of this element could be compromised by degradation processes. To investigate such changes, experimental ageing test analyzing the effects of acid rain aggression on different marble samples is carried out in this research. Marbles’ reactions are studied in terms of: lightness, gloss, and Distinctness Of Image. The main findings demonstrate how the acids hugely degrade both the marble typologies and quantify the modifications.

Abstract
Marble thin panels are widely used for external building envelope application, due to their original light transparency effects during day-time and night-time. Considering their application in polluted environments and the interaction with aggressive agents, the aesthetical characteristics of this element could be compromised by degradation processes. To investigate such changes, experimental ageing test analyzing the effects of acid rain aggression on different marble samples is carried out in this research. Marbles’ reactions are studied in terms of: lightness, gloss, and Distinctness Of Image. The main findings demonstrate how the acids hugely degrade both the marble typologies and quantify the modifications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
