Title: Concrete Tensile Strength of Hollow Cubes Subjected to Water Pressure

Abstract:Researchers have struggled to come up with accurate and convenient tools to measure concrete strength in tension. Several indirect experimental tests of concrete in tension are used to measure the concrete strength in tension, including the splitting test and the beam test. None of the indirect methods measures the true tensile strength of concrete; at the same time, there is no widely acceptable direct tensile test. In this study, a new testing procedure is introduced to measure the concrete strength in tension by subjecting a hollow concrete cube to internal water pressure. The hollow concrete cube will fail due to excessive circumferential/hoop stress, which is pure tensile stress. The maximum hoop stress that causes the hollow cube to fail in tension is taken as the concrete tensile strength. The hollow cubes were subjected to internal water pressure. New simulation theoretical finite element model was also
developed to validate the experimental results.
