The rammed earth technique, in all its variants, is widespread all over the world. This enormously prevalent building technique harbours an important richness Editors Rammed Earth of varieties both in application and in materials used. Interventions on historical rammed earth buildings have also been carried out in all the geographical areas Mileto where these structures are found. This historical heritage has undergone diverse Vegas forms of reconstruction, conservation, repair, substitution and/or structural consolidation. The different criteria applied require different techniques, Cristini materials or forms of intervention. The results of the interventions have also Conservation been manifold, both in terms of the impact on the building and the technical and material durability. With a view to these issues, this book deals with rammed earth architecture and its restoration, and, in a more general sense, with the construction techniques and restoration of all earthen structures. Rammed Earth Conservation will be a valuable source of information for Editors: academics and professionals in the fields of Civil Engineering, Construction and Building Engineering and Architecture.
