Behavior of Reinforced Concrete with Recycled Tyre Polymer Fibers After Fire Exposure

Negative effects such as spalling caused by fire exposure of concrete structures can be diminished by incorporation of polypropylene (PP) fibers. Due to various initiatives taken worldwide in an attempt to convert waste materials into new products, the main objective of this research is to quantify contribution of recycled tyre polymer (RTP) fibers as replacement for PP fibers. In the scope of presented research ordinary concrete, concrete with 1kg/m3 of PP fibers and concrete with 5, 10 and 15 kg/m3 of RTP fibers were considered. Analysis encompassed mechanical properties of unheated concrete and after the exposure to elevated temperatures up to 800°C.
