Abstract

Highlights: A large knowledge about air lime mortars is referred. Raw materials, characteristics, degradation factors and durability are addressed. Results obtained by about one hundred authors are reviewed and compiled. Lacks in knowledge and needs of research on air lime mortars are identified. Human factor, time factor and local issues are identified for further study. Abstract: Air lime mortars were used in construction since immemorial times until at least the beginning of the 20th century. This material may tell the history of construction, in large parts of the world, as perhaps no other may. To retrieve the lost knowledge of air lime mortars preparation techniques and application methodologies, many scientific studies were carried out, beginning with the analysis of old mortars and the study of old treatises and continuing with research about new air lime mortars. In spite of all those efforts and of the evidences that lime mortars are the most adequate for the conservation of old buildings, their use in conservation interventions is still rare. What is lacking in knowledge in order to make it possible their generalized use? And what is lacking in action?
