Characterization of Restorative Mortars for Application in The Pasargadae World Heritage Site

In this study, considerations for design, characterization, and in-situ application of sustainable materials for restorative use in the Pasargadae world heritage site are discussed. Based on some prior studies on sustainable waste-based restorative mortars, air lime mortars were made from lime putty, mixture of stones from the site, and additive sesame oils. The mortar samples were characterized in terms of microstructure, carbonation rate, hydric properties, and durability. The characterization aimed at compatibility assessment of mortars with a real situation. Considering the variety of natural conditions parameters compared to the laboratory, the mortar samples were also characterized in the site conditions. The results suggested the laboratory characterization, if done properly, can provide a promising degree of representation for the field conditions.
