Da Almedina à Feliz Lusitânia: personagens do patrimônio
(Universidade Federal do Pará, 2011) MIRANDA, Cybelle Salvador
This article compares the forms of appropriation of restored historic places in cities whose cultures and morphologies share similarities, because of their colonial history. Combining iconographic research and interviews, a comparison between the historical downtown in both Coimbra and Belém enabled me to trace a parallel between both cities. I have selected the walled area of Almedida (Coimbra) and the vicinities of Feliz Lusitânia (Belém) in order to investigate the perceptions of the people who lived there and were involved in the restoration processes. I have highlighted the impacts of the remodeling in their daily lives.

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/7501959623721607
The 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.

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/3432832117667434
Concrete 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.
