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

Abstract

Air lime mortars with addition of two types of sesame cooking oil were synthesized and cured in two different conditions: laboratory and natural climatic conditions of the Pasargadae and Persepolis World Heritage Sites. For the mortars cured in the laboratory, addition of oils in the mortar induced hydrophobic effects, but it adversely affected on permeability values and carbonation rates. However, the air lime mortars cured in the site conditions demonstrated increment in their hydrophobicity and superficial durability without retarding their setting time and adverse effects on their calcium carbonate formation values, due to various climatic parameters existing in natural outdoor conditions.

Optimization of Hydrophobic Lime Putty Enriched with Sesame Oil for In-situ Preparation of Restoration Mortars

“…This was valid when mortars were cured whether in laboratory conditions or natural ambient [ 8 ]. However, formulation of oiled lime mortars in the application site is a problematic action [ 9 ] as dispersion of oils in the immense quantity of martial might not be easily feasible. Hence, this issue can lead to a different nal performance of oiled mortars from laboratory to site.…”

“…The best compressive strength result was achieved with a ternary binder with both slag and fly ash, and this result was probably produced by the synergetic effects of slag hydration and fly ash pozzolanic reactions. On the other hand, Pahlavan et al [5] synthesized air lime mortars via the addition of two types of sesame cooking oil. These were cured in the laboratory and natural climatic conditions of the Pasargadae and Persepolis World Heritage Sites.…”
