ESTUDO DE CASO: DIFICULDADES, MÉTODOS E TÉCNICAS APLICADAS PARA A CONCRETAGEM DE UM EDIFÍCIO DE 54 PAVIMENTOS NA CIDADE DE GOIÂNIA/GO

Case study: challenges, methods, and techniques applied for the concreting of a 54-story building-complementem

Abstract

With the increasing verticalization of cities, the construction of tall buildings is becoming more and more prevalent in Brazil. It is known that the technical team is challenged to analyze and thus propose suitable solutions to address the difficulties that may arise during the execution of this type of construction. With this objective in mind, a case study was conducted on a 54-story building located in Goiânia-GO. Initially, the inherent challenges in the concrete casting process were investigated, as well as the solutions applied during the concreting phase. In this context, it is worth noting that the main challenges were observed from the thirtieth floor onwards, namely the rupture of the casting pipes, concrete segregation and rebound, and complications with the initial type of pump used for concrete placement. Among the applied solutions, the use of Ultrasonic Plate Thickness Gauge, alteration of the concrete mix design, implementation of self-compacting concrete, and replacement of the pump type stand out. The research contributes to both the scientific and technical branches of Civil Engineering. As a result of this study, new solutions can be identified and studied, and the proposed research findings can enhance future executions of this type of building.
