- Title
Heritage Stone 3. Degradation Patterns of Stone Used in Historic Buildings in Brazil.
- Authors
Costa, A. G.
- Abstract
Brazil's heritage buildings were built using different types of natural stone, including sandstone, limestone, quartzite, granite, gneiss, steatite (soapstone) and schist. Historic buildings are located in cities such as Recife, Olinda, Salvador, Rio de Janeiro, Congonhas and Ouro Preto; some are over 300 years old. They show evidence of different alteration and decay processes, with the latter leading to a loss of value because of physical and chemical modifications in intrinsic properties of the natural stones used. Consequently, these buildings function as open-air laboratories, and contribute to the study of deterioration in such monuments. On going investigation of alteration and decay reveals that they are affected by a diverse group of processes that are, in part, influenced by lithological factors. This understanding will contribute to the choice of preservation methods that will be applied in order to arrest degradation.
