Use of common fibers, in addition to increasing ductility, toughness, first point cracking, and ultimate strain, plays a major role in preventing shrinkage and thermal cracks. The role of temperature in fiber bridging and change of material structure has been investigated in previous studies. Use of waste materials in structural materials can decrease further pollution of ecosystem. On the other hand, increase in oil and polymer-based waste materials, caused some concern in the international community because of the adverse environmental impact of this material. For this reason, in this research, steel fiber (0.4, 0.5 and 0.6), Polypropylene fiber (0.03, 0.05 and 0.1), and recycled Polyethylene terephthalate (PET) fiber (0.2, 0.3 and 0.4) percent of the concrete mixture volume were used. The results of the rheological (V-funnel, T50, Slump and L-Box), mechanical properties (e.g., compressive, flexural, and splitting tensile strength) and Ultrasonic Pulse Velocity (UPV) Test of self-compacting concrete exposed to temperatures of 20, 200, 300, 400, and
