Previous issue date: 2014-05-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The search for cultural heritage preservation should be a constant, in order to minimize the lost of historical and cultural identity of a country. As part of this cultural heritage, highlights the importance of historical buildings. For the principles of restoration are met its important to know the state of conservation and the existing materials. Given the above, this work aims to study the pathological manifestations of the mortar coating from the Grupo Escolar Augusto Severo. For this, was conducted historical survey of the building, on-site visits with visual observation, collecting samples of mortar coating and characterization through visual and laboratory analysis, XRF, XRD, TG/DTG, OM and SEM-EDS. From the observations, pathological manifestations were found as: cracks, detachment of the coating, dirt, use of inappropriate material basis of cement, efflorescence, mold and mildew and also incompatible material base of cement. It was found that the pathological manifestations were intensified due to lack of coverage in some spots and especially the abandonment of the building, that many years does not have restoration or any other type of preventive and corrective maintenance. The results of laboratory tests indicated that the mortars studied are based on lime, with calcitic nature, and siliceous aggregate, with the presence of clay in two samples. From the samples collected, two are composed of lime, sand and clay and two by lime and sand. In this regard, it is important to conduct periodic inspections and maintenance, as well as carrying out restoration with use of material compatible with the original / A busca pela preserva??o do patrim?nio cultural deve ser uma constante, para que n?o haja a perda da identidade hist?rica e cultural de um pa?s. Como parte deste patrim?nio cultural, destaca-se a import?ncia das edifica??es hist?ricas. Para que os princ?pios de restauro sejam atendidos ? de suma import?ncia conhecer o estado de conserva??o desses bens e os materiais existentes. Diante do exposto, este trabalho tem como objetivo estudar as manifesta??es patol?gicas presentes nos revestimentos argamassados, bem como caracterizar as argamassas, de maior valor patrimonial, do Grupo Escolar Augusto Severo. Para isso, foi realizado um levantamento hist?rico da edifica??o, visitas in loco com observa??o visual e registro fotogr?fico, coleta de amostras de argamassas de revestimento e caracteriza??o por meio de an?lise visual e laboratorial, FRX, DRX, TG/DTG e MEV-EDS. A partir das observa??es realizadas, foram identificadas manifesta??es patol?gicas como: fissuras, desprendimento do revestimento, sujidade, efloresc?ncia, mofo e bolor, al?m da utiliza??o de material inadequado ? base de cimento. Constatou-se que as manifesta??es patol?gicas foram intensificadas devido ? falta de cobertura em alguns pontos e, sobretudo pelo abandono da edifica??o, que h? muitos anos n?o passa por restaura??o ou qualquer outro tipo de manuten??o preventiva e corretiva. Os resultados das t?cnicas em laborat?rio indicaram que as argamassas estudadas s?o ? base de cal, de natureza calc?tica, e agregado silicoso, com presen?a de argila em duas amostras. Das amostras coletadas, duas s?o compostas por cal, areia e argila e duas por cal e areia. Neste sentido, ressalta-se que ? de relevante import?ncia a realiza??o de inspe??es e manuten??es peri?dicas, bem como a realiza??o de restaura??o com a utiliza??o de material compat?vel com o original
