The application of lime mortar for the purpose of bonding, protecting, and enhancing constructions has been a common activity throughout history. Understanding the mechanical properties and carbonation process of lime mortar is essential for the successful repair and conservation of architectural heritage. The compatibility and durability of lime mortar within architectural history require an analysis of related mechanisms to guarantee its suitability for modern settings. This research delineates the mechanical properties of lime mortar and examines the mechanism of its carbonization. The main objective of the present study is to study the properties of lime mortar with the addition of silica fume. From the test results, the properties such as consistency limit, setting time and flow rate was analyzed. Also, the compressive strength was increased around 38% with the addition of silica fume. The results of this study will help to utilize lime mortar with additives a s a repair material for historical structures and as masonry mortar.

Key Words: carbonation, compatibility, durability, lime mortar and silica fume
