MANIFESTAÇÕES E SINTOMAS PATOLÓGICOS EM ESTRUTURAS DE CONCRETO ARMADO NA CONSTRUÇÃO CIVIL

Abstract

This work describes about the Structural Pathologies in Construction Engineering. The objective is to identify the manifestations and pathological symptoms in reinforced concrete structures in the construction process (execution phase) of a closed condominium in Belo Horizonte-MG, highlighting the causes, consequences, solutions or necessary treatments and verifying the influence of hand quality of work employed. The single case study was adopted as methodology, supported by the review of the bibliography and updated literature. The collection of collected data relied on participant observation, and the results were interpreted and described. It was identified that the most common manifestations and pathological symptoms in reinforced concrete structures in the case under study were: segregation, resistance and cracks. It was noticed that the causes of the pathologies identified and analyzed were related to the (lack of quality of) labor involved in the execution and supervision of concreting. Thus, as consequences of pathological manifestations, both the disqualification of the workforce executing the construction, and the designers (engineers) who should take care of the supervision and guarantee of compliance with their projects and specifications were attributed. It was concluded that Civil Engineering must stick to the quality of the stages of buildings in Civil Construction, aiming at more assertive projects, the application of the best techniques, precise and supervised execution, the use of reliable materials, and investment in skilled labor. Qualified workmanship to guarantee the safety and quality of the building and to obtain the expected performance throughout its useful life.
