Evaluation of pathological manifestations in concrete structural floor destined to the operation of vehicles in garage: case study of residential building located in the federal district

Abstract

The origin of pathological problems in the structure indicates in general the existence of faults during the execution of a phase of construction, it also indicates faults in the quality control system of one or more activities. The polished concrete floor is a surface subjected to daily traffic of vehicles and the action of chemical substances, in this way should have as main attributes the durability, hardness and strength. This research has the intention to study the case of pathological changes found by polished concrete floor of the garage of the Condominio Via Parque da Cidade, Setor Sudoeste-Brasilia/DF. In addition, the project presents proposals for corrective action identified these pathologies. The same were mainly identified by visual inspection, but is made necessary the building’s historical analysis and finally percussion tests, extraction and rupture of the test piece of sample, proving the initial opinion. It could be sure that the observed cracks are due to poor adhesion between layers on the garage floor, as the exacerbation of such problems can be blamed on construction execution addictions. As corrective action is recommended the demolition of the current floor and execution of the entire reconstruction process of the polished concrete floor, according to a new project that has the necessary guidelines to prevent the return of pathology and so there is the performance of recovery the same.
