One of the latest advancements in concrete technology is Ultra-High Strength Concrete (UHSC). UHSC is defined as concretes attaining compressive strength exceeding (100MPa). This concrete is a fiber-reinforced, densely packed concrete material which exhibits increased mechanical performance and superior durability as compared to normal and high strength concretes. In the present study, an experimental work was performed to investigate the behavior of Ultra High Strength Reinforced Concrete beams in shear and flexure. Total of twelve simply supported rectangular beams were casted with cross section dimension (150 × 250)mm and span of (2150 mm). Three direct shear specimens were also prepared and tested to study the shear force transfer behavior of ultra high strength concrete.The mechanical properties such as compressive strength, compressive stress strain curve, modulus of elasticity, and tensile splitting strength of concrete were investigated. The average values of compressive and tensile strengths of UHSC were 124 N/mm2 and 7 MPa respectively.
