Preliminary Valorization of Climatic Conditions Effects on Curing of Air Lime-Based Mortars for Restorative Applications in the Pasargadae and Persepolis World Heritage Sites

Climatic conditions significantly influence the performance of air lime-based mortars, enhancing their hydrophobicity and superficial durability without adverse effects on setting time or calcium carbonate formation. A study found that adding sesame cooking oil to these mortars improved their properties when cured under natural outdoor conditions at UNESCO World Heritage Sites like Pasargadae and Persepolis, unlike in controlled laboratory settings where such additions negatively impacted permeability and carbonation rates. The research involved synthesizing mortars with oil additives and comparing their curing outcomes under different environmental parameters.
