The present work focuses on the diagnosis of the damage induced by air multi-pollutants on the Centennial Hall, situated in one of the most industrialized and polluted regions of Poland, in close neighborhood of coal power stations. In order to investigate the impact of multi-pollutants on the cement built heritage samples of damage layer and underlying material were collected from the building, taking into account rain exposure (sheltered, partly sheltered and washed out areas) and analysed by range of analytical techniques: optical and scanning electron microscopy, X ray diffractometry, differential and gravimetric thermal analysis, ion chromatography, flash combustion/gas chromatographic analysis, inductively coupled plasma-optical emission spectrometer. The results obtained show that the surface deterioration of the Centennial Hall is mainly caused by deposition of SO2 and fly ash from coal combustion, and subsequent interaction with the cement components. These results for the first time demonstrate the impact of coal power stations on black crust formation on cementitious materials.

Abstract
The present work focuses on the diagnosis of the damage induced by air multi-pollutants on the Centennial Hall, situated in one of the most industrialized and polluted regions of Poland, in close neighborhood of coal power stations. In order to investigate the impact of multi-pollutants on the cement built heritage samples of damage layer and underlying material were collected from the building, taking into account rain exposure (sheltered, partly sheltered and washed out areas) and analysed by range of analytical techniques: optical and scanning electron microscopy, X ray diffractometry, differential and gravimetric thermal analysis, ion chromatography, flash combustion/gas chromatographic analysis, inductively coupled plasma-optical emission spectrometer. The results obtained show that the surface deterioration of the Centennial Hall is mainly caused by deposition of SO2 and fly ash from coal combustion, and subsequent interaction with the cement components. These results for the first time demonstrate the impact of coal power stations on black crust formation on cementitious materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
