Resumo: | The study of materials used in ancient buildings provides a means to shed light on traditional building practices of past societies, but can serve as inspiration to tackle challenges faced by the current generation. Characterising earth-based structures and finishing elements is part of this mission, especially at a time when earthen architecture is the subject of renewed interest due to its many advantages, particularly in terms of sustainability. This paper considers a set of historical earthen houses built during the first phase of the coffee economy (1820-1880) in the middleParaíba do Sul River valley, in southeastern Brazil. Physical (colour and texture) and chemical (FTIR, TGA, XRF, and XRD) analyses performed on a large set of mortar and local soil samples collected in the region formed the basis for discussing possible soil selection criteria as raw materials, texture solutions, and the stabilisation strategy of the final product. This last aspect implied the addition of small quantities of lime, in the case of external renders and more sporadically in plasters, without the use of fibres or organic additives. Chemical data and historical sources suggest that the rawmaterials used for this purpose were probably brought to the region from coastal areas. |

Caracterizar estruturas e elementos de acabamento das edificações construídas com terra crua faz parte dessa missão, especialmente numa altura em que a arquitetura com terra é objeto de interesse renovado devido às muitas vantagens, particularmente em termos de sustentabilidade. Este artigo considera um conjunto de construções históricas edificadas em terra crua durante a primeira fase da economia do café (1820-1880) no trecho paulista do vale do rio Paraíbado Sul. Análises físicas (cor e textura) e químicas (FTIR, TGA, XRF e XRD) realizadas sobre um grande conjunto de amostras de argamassas e de solos locais recolhidas na região formarama base para discutir possíveis critérios de seleção de solo como matéria-prima, soluções de textura e a estratégia de estabilização do produto final. Esse último aspecto implicava a adição de pequenas quantidades de cal, no caso de rebocos externos e, mais esporadicamente, nos revestimentos internos, sem a utilização de fibras ou aditivos orgânicos. Dados químicos e fonteshistóricas sugerem que a matéria-prima utilizada para esse fim foi provavelmente trazida para a região a partir de zonas costeiras.Universidade de São Paulo.
