Mechanical Performance of Ultra-High Performance Concrete for Bridge Applications

Ultra-high Performance Concrete (UHPC) is an upcoming type of cement composites, which now a days getting extensive attention and is particularly applied to bridge engineering area, on account of its superior mechanical performance and durability. With introduction of Ultra-High Performance Concrete, there is need to develop equation and relationship which can predict modulus of elasticity, flexural and split tensile strength of Ultra-High Performance Concrete using indigenous materials. The study is done by analysing experimentally obtained test results of a total 120 specimens for flexural strength, 120 specimens for split tensile strength and 100 samples for modulus of elasticity of concrete. Based on the experimental results an empirical equation is proposed for the prediction of modulus of elasticity, flexural and split tensile strength for strength range of 15 to 150 MPa and is compared with the empirical equations available in the different International standards.
