Caracterização do aço CA50 disponível no comércio de Jataí-GO

Abstract

Since its discovery, steel is a material that has undergone changes in its manufacture, chemical composition and properties over the years, in order to obtain satisfactory characteristics and meet certain utilities delivered to it. CA-50 steel is a very valuable material in the field of civil construction, which opened the doors to a wide market of civil construction and architecture, being able to execute projects of works of art considered impossible before the discovery of reinforced concrete. This present work seeks to evaluate some of the common CA-50 steel brands in the works of the city of Jataí-GO, thus being able to contribute to the local civil construction, revealing the physical and mechanical characteristics of the usual steels in the works of the locality. The mechanical behavior of the bars will be revealed from tensile tests and their results will be presented to the reader in the form of reports and graphs, thus being able to be easily compared with each other and with the NBR 7480:2007, specifications for steel intended for reinforcement for reinforced concrete structures.
