Análise das propriedades mecânicas do concreto estrutural com adição de sobras de arame recozido liso

Abstract

It is known that the generation of by-products in the construction industry is, although undesirable, inevitable in most cases. The destination of these by-products, in addition to being economically harmful, usually does not occur properly. With greater competitiveness in the sector and the environmental issue gaining due importance, ideas focused on lean thinking stand out daily. In this sense, despite having relevant commercial value, the smooth annealed wires used for reinforcement moorings have significant waste within the construction sites, even those containing satisfactory mechanical properties to the traction. In contrast, it is known that traction is the least favored property of concrete, which is one of the most consumed materials in the world, given the favorable technical impact it provides. Thus, it was observed the mechanical deficit to the traction of concrete and the waste of smooth recooked wire, and in a similar way to the thought used for the reinforced concrete with steel fibers, it was studied mechanical behavior of the concrete with the addition of smooth recooked wire leftovers, in the contents of 0%, 5.50% and 11.00% depending on the cement mass. Axial and diametrical compression tests were also carried out to check the resistance to compression and diametrical traction at 7 and 28 days, in which satisfactory results are obtained for the 5.5% content of the addition of the flat annealed wire in the concrete.
