Abstract


This work is part of an International Cooperation Agreement for the conservation of historical monuments made of reinforced concrete in Brasilia. This research is based on a routine inspection of the National Theatre of Brasilia, a city recognized by UNESCO in 1987 as world cultural heritage. The structure, entirely made of reinforced concrete, was conceived by architect Oscar Niemeyer, and has a total of 48 m of height and 42,000 m2 of constructed area. After examining the available documentation, the existing damage was then identified and mapped. The concrete shows a good state of conservation, with the exception of some regions of the structure: the damages found were exposed armature, oxidation of armature, infiltration, mold and efflorescence.

Keywords
