CASOS REAIS DE OBRA COM CONCRETAGEM SUBAQUÁTICA

Underwater concreting is a technique widely used in infrastructure works, such as bridges, dams, ports and foundations in flooded environments and its durability is directly dependent on the interaction of concrete with the environment. This happens mainly due to the pathologies of the environment, whether by chemical agents, physical agents and biological agents. The main objective of the study is to understand some real cases and the techniques used in their constructions, presenting a theoretical overview of the use of methods such as tremie and submerged pockets, as well as normative aspects that control the quality of the specificity that involves civil engineering. The definition of a checklist of the steps with important items for an accurate diagnosis will also serve as an example for civil engineers when executing or evaluating work cases with underwater concreting. The Real Case Study highlights the work and takes into account the conditions of the environment, the material used, the methodologies used, the control of the problem presented in the case and also the results obtained with the possible insights for future planning. The case study methodology includes the study of different situations in concretes where diagnostic intervention and technical support were required.
