Item Acesso aberto (Open Access) Deterioração das pedras da arquitetura mortuária do cemitério Nossa Senhora da Soledade(Universidade Federal do Pará, 2014-10-31) SILVA, Pâmela Anne Bahia Vieira da; ANGÉLICA, Rômulo Simões; SANJAD, Thais Alessandra Bastos Caminha; http://lattes.cnpq.br/8950586647715771; http://lattes.cnpq.br/7501959623721607The city of Belém do Pará contains an area that harbors numerous stone monuments which mark and identify the Belém’s 19th century society. This area is the Cemetery of Soledade, which now function as an outdoor museum. Besides the weathering, wich makes stones change constantly, Soledade has suffered with looting and vandalism throughout its more than 150 years of existence. The presence of deterioration on the stones of tombs and mausoleums of the first public cemetery in Belém damages the quality and integrity of the material, interfering negatively in the reading of the spatial image. The Cemetery has been listed as a National Heritage Landscape since 1964 by IPHAN. Considering the importance of conservation and restoration of ancient buildings and monuments to preserve the memory of a society, this research sought to assess the deterioration by weathering and anthropogenic origin in the different stones used in tombs and mausoleums of Cemetery of Soledade. In order to generate subsidies for the conservation and restoration of these stones, the characteristics of rocks used, its state changes and the causes of deterioration were assessed. The analysis and technological investigations allowed for the identification of granite, limestone and marble and for the determination of agents and mechanisms of deterioration such as chemical action, high temperatures and microbiological action. The diagnosis of the conservation condition throrough the mapping of damages based on the Illustrated Glossary on Stone Deterioration Patterns of ICOMOS confirmed the advanced level of the pathological manifestations on the surfaces of stones, which also present lack of internal cohesion and discontinuities according with ultrasound results. To contribute to future conservation actions, restoration procedure tests to clean the monuments such as the polishing and application of bentonite plaster were performed efficiently. The results highlight the urgent need for conservation actions to reduce the rate of deterioration and mitigate the current advanced state of the same. With the data obtained, this study try to be an alert to the the situation of abandonment of the Cemetery of Soledade, promoting the importance of keeping it preserved for future generations.Item Acesso aberto (Open Access) Mosaicos de Belém: história e conservação(Universidade Federal do Pará, 2013-08-30) TOSCANO, Thais Zumero; SANJAD, Thais Alessandra Bastos Caminha; http://lattes.cnpq.br/8950586647715771The mosaic is an ancient art which impacts the history of civilizations. The city of Belém po-sesses a beautiful, peculiar and rare acquis. For being so uncommon, it is not regarded as an autonomous or as well integrated art. This fact becomes visible due to the lack of biblio-graphical data and registries on the theme. This research aims to demonstrate such facts by means of a historical contextualization and a literature review that covers techniques, con-servation, common damages and frequent pathological conditions. The main focus of this study is the mosaic collection of the city of Belém /Pará. It identifies techniques, typologies, datings, physical constitutive characteristics of the employed materials. Materials and me-thods are presented starting from the samples selected. After the analysis of these samples with their features and physical chracateristics by optic microscopy the study comes to its final part, the conclusions based on the necessary preservation of this cultural asset which integrates the memory of the city.Item Acesso aberto (Open Access) A pintura de quadratura landiana em Belém do Pará(Universidade Federal do Pará, 2013-09-30) DINIZ, Virgínia Lúcia Guerreiro; SANJAD, Thais Alessandra Bastos Caminha; http://lattes.cnpq.br/8950586647715771In the second half of the eighteenth century, the city of Belém went through a great economic expansion, which reflected positively in its architecture, with the erection of impressive religious temples in the current historical center, such as São João Batista Church. This work examined the quadrature painting performed by the architect Antônio Landi in São João Batista Church’s interior, in Belém, to identify the paint used in that rare painting, based on the artist’s claim that he used the pigment extracted from Arrabidaea chica (H & B) Verlot, popularly known as carajiru, and the changing process this pigment went through. Therefore, it was possible to get important data for its preservation and restoration. The study was divided into three stages: first, there was a historical research focused on literary works about paints, pigments and dyes used in religious architecture during the Amazonian colonial period; on the influence of the religious orders on the decoration of the temples; on Landi’s educational background and his works in Belém; and on the technique called quadrature painting. During this stage, the damage in the painting was mapped out and the color patterns were assessed through colorimetry, and the temperature of the painted walls was measured with an infrared camera. The second stage consisted of a laboratory analysis of the paint used by Landi and the pigment extracted from carajiru through optical microscopy, scanning electron microscopy, X-ray diffractometer and infrared spectrometer. The data surveyed allowed the identification and comparison of the materials used in quadrature painting. Finally an experiment with the paint produced from the pigment extracted from carajiru. The historical research contributed to the comprehension of the properties of the paint, pigments and dyes. The interdisciplinary study enabled the conduct of technological procedures, and allowed the development of diagnoses that are helpful to establish preventive conservation measures and proposals for future restoration interventions.Item Acesso aberto (Open Access) Restauração do concreto aparente: estudo tecnológico para salvaguarda de edificações com tendências modernistas(Universidade Federal do Pará, 2013-03-21) OLIVEIRA, Djanira Cabral Viégas Borges da Cruz; PAES, Isaura Nazaré Lobato; SANJAD, Thais Alessandra Bastos Caminha; http://lattes.cnpq.br/8950586647715771; http://lattes.cnpq.br/3432832117667434Concrete is basically formed by mixed cement, water, sand and stone, and has emerged as a building material to replace wood, stone, brick and even structural steel, but only in the twentieth century its aesthetic beauty was recognized. The modernism appropriated the new constructive technology and its plastic possibilities and splited definitively with the passed styles. Influenced by the schools of Rio and São Paulo, architects and engineers who built at Belém left a legacy of unfinished concrete constructions, which unfortunately is being threatened by the lack of specific care, since many interventions are made in a random and misguided way. Therefore, the aim of this research is to study the unfinished concrete under the historical and technological aspects in order to develop a methodology for restoration of areas with gaps, considering aspects such as color, texture and strength, seeking a compatible material to the original concrete. The study was conducted in three different steps: 1) Historical Research, 2) Field Research; 3) Research Laboratory. The materials of this study correspond to samples collected in three buildings and laboratory samples. The physical characterization of the samples allowed to find the approximated trace of the old concrete of 1:3 and the strength of the material, which is approximately 22MPa. The chemical and mineralogical characterization indicated that the original material has been suffering process of mineralogical transformation evidenced by the presence of polymorphs of calcium carbonate (CaCO3) and allowed to understand that the aggregates used in the composition of the material may have quartz or gravel origin. It was also observed that the color and texture of the material varies depending on the type of cement and aggregate used in the production of concrete. From the identification of the principle features of the original materials was developed a methodology for producing a mortar for restoration with properties similar to the antique material. The results as color, texture, and strength were satisfactory, because the values established by rule were accomplished and were also compatible to the appearance of the original concrete, allowing restoring the image of the building and achieving the proposed objectives.Item Acesso aberto (Open Access) O vidro e os vitrais de edificações históricas de Belém: patologias e conservação(Universidade Federal do Pará, 2013-09-05) PINTO, Amanda Monteiro Corrêa; SANJAD, Thais Alessandra Bastos Caminha; http://lattes.cnpq.br/8950586647715771The application of glass in Belém’s architecture, at first, was restricted to large buildings, in the late XIXth century, reaching its peak only in the next century, during the eclectic movement, as an import issue. However, face to the overexposure to the weather and improper substitutions, ancient glasses are gradually disappearing, almost being impossible to documentate it properly. In order to safeguard this material, the main objective of this research is to investigate technologically glasses and stained-glasses physico-chemical characteristics from buildings of Belém and its damages caused by weather conditions. Selected samples were characterized through optical microscopy, and scanning electron microscopy with energy dispersive X-ray microanalysis (SEM/EDX), concomitantly with the execution of graphic in order to do damage diagnosis and to identify most frequent pathologies. Therewith it was possible to verify that samples present a moderated level of degradation as considerable deposits of soot and discoloration and that the biofilm which develops at the glass surface is responsible for its opacity, that fact origins moderate corrosion and stains. FRX data revealed that all samples as soda-lime glass with 70% of SiO2. Resulting data will be important to subsidize conservation and restoration practices on historical glasses and stained-glasses according to local weather conditions.
