Recuperação de estruturas de concreto armado : estudo de caso de recomposição de vigas e pilares de equipamento na Mina de Vargem Grande

Abstract

This study aims to report on the recovery of reinforced concrete structures: possible causes that lead to their wear and tear and the main ways of treating them. As one of the most used methods in civil construction, the study and research around this theme are recurrent. The use of low quality materials used in the works, the low-skilled workforce and the lack of maintenance of the structures are the main factors cited as causing damage to them. To do so, we resorted to explanatory research with a case study of a work that took place in the Vargem Grande Mine, in Vale. The results obtained were: need for immediate intervention, with the support of different sectors of Vale, due to wear due to abrasion of the beams and pillars. Thus, a strategic plan was created to act on the asset, followed by an efficient execution plan, recovering 100% of the construction.
