| dc.description.abstract | This paper presents the results of an experimental research on the ambient and high-temperature compressive strength of concretes made with steel or textile fibers from recycled tires. The studied compositions included a reference (RC), two textile fibers (TF) and two steel fibers (SF) concretes. The other aggregates were crushed ones and natural sand and the cement content 400kg/m3 for a water/cement ratio of 0.31. The specimens were tested in compression for different levels of temperature (20, 300, 500 and 700ºC). The specimens were heated, under loading, inside a tubular furnace accomplished to a tensile/compression machine. During the heating, the specimens were subjected to a constant loading level of 0.5fcd. The results of this experimental program showed that steel and textile fibers are a good solution in the compressive behavior of the concrete regarding to cracking control. However, some difficulties in the concrete preparation were experienced as the mixing of fibers. | pt_PT |
