Abstract—This work is a part of industrial waste development program. It is devoted to the study of recyclability, as reinforcement for concrete, of chips resulting from the machining of steel parts. We're interested in this study to the rheological behavior of chips reinforced fresh concrete and its mechanical behavior at a young age. The evaluation of the workability with the LCL workabilimeter showed that optimal sand over gravel ratios are S/G = 0.8. Mechanical characterization tests (direct tension, compressive and flexural) show that the mechanical properties of chips concrete are comparable to those of the two selected reference concretes (concrete reinforced with conventional fibers: Eurosteel fibers corrugated and Dramix fibers). Chips provide a significant increase in strength and some ductility in the post-failure behavior of the composite to concrete witness. Recycling chips as reinforcement for concrete can be favorably considered.
Index Terms—Concrete, fiber, recyclability, direct tension.
