Tire waste is a serious problem for environment, health, and safety due to growing in volumes of its production. Recycling and recovery of waste tire as a useful product has a real importance. In this study, pyrolytic liquid obtained by waste tire pyrolysis was incorporated into MgO-C refractory as a binder to investigate the effects of its utilization on the thermal shock resistance of MgO-C refractories. The physical properties such as open porosities, densities, and mechanical properties such as Cold Crushing Strength (CCS) and 3-Bending Strength were investigated before and after thermal shock test at 1000 °C. The microstructure and fracture surfaces were characterized by using the Scanning Electron Microscopy (SEM). Elemental analysis of those refractories were examined by the Energy Dispersive X-Ray (EDX) analysis. Experimental studies showed that refractories produced by the use of pyrolytic liquid as a binder could have less reduction in their strength values after the thermal shock test.
