The contemporary innovation in concrete technology is ultra-high-performance concrete (UHPC). In this work, mechanical properties of UHPC are studied at ambient terrestrial temperature conditions. Specimens are prepared under laboratory environments maintaining the temperature of -25°C, -5°C, 15°C, 35°C, and 55°C. A freeze thaw chamber is utilized to condition the specimens at specified temperatures. Compressive strength, flexural strength, toughness, and modulus of elasticity are determined under varying temperature and steel fiber volume content. The results indicate that both temperature and steel fibers have effect on the mechanical properties of UHPC. The flexural and compressive strength show an opposite trend of strength under the temperature variations. Effect on modulus of elasticity is similar to compressive strength. Numerical relations are developed among modulus of elasticity and compressive strength isolating both temperature and steel fiber volume.
