The use of steel fiber reinforced concrete is commonly associated with the design of pavements, especially industrial floors, then, this work approach the effects of using steel chips residue in concrete, acting as a substitute for the fiber components in these structures, offering an alternative material for the reinforcement process of them and proposing a new destination for this type of steel waste. An analysis is made by comparing two industrial pavement projects, which will be built in concrete and with equal dimensions, analyzing the maximum stress resisted by them, both differing only in their composition, the first being reinforced with fibers of commercial steel and the second using the steel chips as a replacement material for the fibers. According to the analysis, the concrete with steel fibers obtained superior results related to the tensile strength in bending, while the steel chip reinforced concrete reached higher results related to compressive strength. Therefore, it is concluded that steel fibers cannot be totally replaced by the chips, however, given the positive effects on compression, it would be of great interest the analyze of the partial replacement of the steel fibers or even the concrete aggregates by the waste steel. Due to the behavior obtained in the tests, it is interesting to further study such replacements aiming the possibility of perform this type of construction with reduced costs, in addition to an eventual reduction of environmental impacts. |
