Resumo(s)
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.
