MANIFESTAÇÕES PATOLÓGICAS EM POSTES DE CONCRETO ARMADO EM DECORRÊNCIA DO SEU PROCESSO PRODUTIVO

Abstract

Pathological manifestations originate mainly in the production process of the poles, and knowing which measures can be taken in the production process to avoid pathological manifestations in the poles is the main problem. The purpose of this research is to elaborate these measures that will mitigate the pathological manifestations present in the company, which are blisters, spots and segregation. For this, the entire fabrication will be evaluated, making a follow-up from the project, assembling the reinforcement, preparing the concrete, launching, densification and storage of the posts, and then the pathological manifestations in the parts that had their manufacturing process will be analyzed. accompanied, verifying the cause and effect relationship, to then elaborate necessary measures to minimize these problems of the produced poles. For this, service verification sheets, test reports and projects provided by the company will be used. That done, it was observed that the company was using burnt oil as a release agent and did not perform an adequate cleaning of the forms, resulting in dark spots on the posts and bubbles, and these still found a relationship with the wrong launch and thickening. Other than that, it was observed that segregation was directly related to the leakage of forms. With this, it is known that the mitigation of the company's pathological manifestations will be done with the use of an appropriate release agent, an adequate cleaning of the forms and its correct sealing, the densification of the concrete with sufficient number of vibrators for its uniform densification together with the training of the employees responsible for concreting the posts.
