A look at the materials of historical interest that build the heritage: notes around a multidimensional experience

Abstract

This article discusses building materials whose application takes us to different times and uses in the built heritage, and which are inseparable from the tastes and cultural influences in the architecture of each location. Some of the materials presented, such as lime and gypsum, have a history of longevity and durability that is a constant challenge for more modern materials, such as cement. Historical materials in century-old, sometimes millenial buildings have resisted diverse adversities, such as floods, fires or earthquakes, and more recently to the human action that, in an attempt to adapt to modern uses and requirements of fashion, technology and comfort, sometimes forgets and goes beyond maintenance, conservation and compatible rehabilitation practices. The article draws the reader’s attention to the tangible and intangible components of the building materials used in the  architectural historical heritage, not forgetting the importance of technical knowledge and dialogue between scientific fields so that this heritage may endure for many centuries to come.
