| Abstract: | Several studies have shown that the degradation of architectural monuments constructed using Tuffeau stones from Val de Loire region of France over a period of time are often related to use of mortars that are not compatible with the Tuffeau stones. For this reason, it is important to ensure physico-chemical compatibility between Tuffeau and the mortar. To alleviate differences in compatibility characteristics, a mortar is prepared from hydrated lime and aggregates obtained from the crushing of Tuffeau stone and used in this study. The key parameters that influence the strength and durability characteristics such as mechanical resistance, water transfer properties, and physico-chemical properties were identified and studied. Based on these studies, recommendations are offered for the preparation of a more compatible mortar that can be used in the construction and restoration of monuments using Tuffeau stone. |
