摘要：Sulfation is one of the main factors of calcareous stone deterioration. In a bid to better preserve our cultural and historic heritage for future generations, the sulfation of limestone from the archeological site of the ancient Roman city of Acinipo was investigated. To simulate sulfation, limestone samples from Acinipo weresubjected to accelerated weathering by chemical attack of SO2 in a humid environment. Weathering provoked the substitution of the calcite matrix for crystals of both calcium sulfate dihydrate and calcium sulfite hemihydrate. The results offer interesting leads into further investigation, while demonstrating the educational utility of the proposed methodology.
