Estudo de caso: dificuldades, métodos e técnicas aplicadas para a concretagem de um edifício de 54 pavimentos

Abstract

With the increasing verticalization of cities, the construction of tall buildings is increasingly becomes a reality in Brazil. It is known that the technical team is challenged to analyze and therefore, propose appropriate solutions to remedy the difficulties that may occur over the course of execution of this type of building. For this purpose, a case study was carried out. of a 54-story building located in Goiânia-GO. Initially, we investigated the difficulties inherent to the process of placing concrete, as well as the solutions applied during the concreting phase. In this context, it is worth reporting that the main difficulties were observed from the thirtieth floor onwards, namely, the rupture of launch pipes, the segregation and the return of the concrete and, the complications with the first type of pump used for placing concrete. Faced with solutions applied, the use of the Plate Thickness Gauge by Ultrasound stands out, the replacement of the mix used, the use of self-compacting concrete and the replacement of the type of pump Of launching.
