Diretrizes para avaliação e tratamento de patologias mais frequentes em pisos de concreto de edificações operacionais dos correios

Abstract

The Post Office operational buildings in Brazil, despite similarities with the most usual logistics activities, presents certain peculiarities in the conditions of storage and load handling, resulting in specific kinds of operations for treatment and delivery of objects, which deserve to be considered in the definition of procedures that contribute to the good performance of concrete floors over their life cycle. In this context, the present work sought to characterize the types of most important operational units of the postal infrastructure of the Post Office, approaching issues related to types of objects, internal flow, layout, equipments used and demands generated, which allowed identifying in a qualitative way the deterioration tendencies on concrete floors depending on the type of unit. From that point on, minimum requirements were established to be met by concrete floors in view of the use required by the activities of the Post Office, regarding the most suitable rigid pavement type, as well as general and specific requirements regarding resistance to demands, abrasion resistance, joints, flatness and leveling. So, it has followed to the definition of important elements for evaluation of pathologies in concrete floors, whose aspects are related to inspections, previous project analysis and instrumentation or tests, with the proper characterization and identification of the most frequent pathologies in the floors of the operational buildings. Finally, procedures were proposed to treat the identified pathologies, under the focus of preventive or corrective maintenance. Thus, the final research product consists in a set of relevant technical information organized to subsidize the evaluation and treatment of pathologies in concrete floors, previously to occupation or during the use of buildings owned or leased.
