Aerial Lime mortars: An introduction and a brief discussion / Argamassas aéreas de cal: Uma introdução e uma breve discussão

In the history, different mortars compositions have been used during ages in masonry structures. Lime was frequently adopted past. summary, there are two main types of lime: hydraulic and non-hydraulic (aerial). The present review deals with second type. Herein, studied lime is specially obtained from thermal decomposition, called calcination, limestone (calcium carbonate (CaCO3). Aerial a complex structural behavior. Several aspects influence material performance. It should be highlighted carbonation process; it modifies properties time.Historic buildings subjected to longer exposures, changing often unknown environmental conditions, affecting work literature about use application aerial mortar as binder historical discussed. There relatively few studies literature, this sense aims contribute theme. text partially based on PhD thesis first author.
