     this paper presents the effect of temperature on thermal and mechanical properties of self-consolidating concrete (scc) and fiber reinforced scc (frscc). for thermal properties specific heat, thermal conductivity, and thermal expansion were measured, whereas for mechanical properties compressive strength, tensile strength and elastic modulus were measured in the temperature range of 20–800 °c. four scc mixes, plain scc, steel, polypropylene, and hybrid fiber reinforced scc were considered in the test program. data from mechanical property tests show that the presence of steel fibers enhances high temperature splitting tensile strength and elastic modulus of scc. also the thermal expansion of frscc is slightly higher than that of scc in 20–1000 °c range. data generated from these tests was utilized to develop simplified relations for expressing thermal and mechanical properties of scc and frscc as a function of temperature.
