Tracing formation and durability of calcite in a Punic–Roman cistern mortar (Pantelleria Island, Italy)

摘要: Ancient hydraulic lime mortar preserves chemical and isotopic signatures that provide important information about historical processing its durability. The distribution composition of calcite in a well-preserved Punic–Roman cistern at Pantelleria Island (Italy) was used to trace the formation conditions, durability, individual periods mortar. analyses stable carbon oxygen isotopes revealed four horizons, D, E, B-1 B-2, from top bottom floor. Volcanic ceramic aggregates were for production horizons E/D B-1/B-2, respectively. All comprise characterized by mean cementation index 1.5 ± 1, constant binder aggregate ratio 0.31 ± 0.01. This suggests standardized highly effective cistern.The high durability formed during carbonation slaked within matrix th...
