ABSTRACT This paper aims to evaluate mineralogical, elemental, and thermal differences among original Roman joint mortars and those used in twentieth-century restoration campaigns taken from different areas at the Herculaneum archaeological site. The purpose is to improve the compatibility of restoration mortars. Roman and modern mortars were studied with petrography, thermal analysis and x-ray fluorescence investigations. The results indicate significant differences between the Roman and modern mortars which could facilitate the degradation process. Roman mortars, in particular, were composed of a coarser aggregate which was present in a lower ratio with binder in comparison with modern mortars.

赫库兰尼姆考古遗址的原始和现代砂浆比较

摘要本文旨在评估原始罗马缝制砂浆与20世纪从赫库兰尼姆考古遗址不同地区进行的修复运动中使用的砂浆之间的矿物学，元素学和热学差异。目的是提高修复砂浆的相容性。罗马和现代迫击炮通过岩石学，热分析和X射线荧光研究进行了研究。结果表明罗马灰浆与现代灰浆之间存在显着差异，这可能有助于降解过程。特别是罗马灰浆由较粗的骨料组成，与现代灰浆相比，骨料与粘结剂的比例较低。
