The Unconfined Compressive Strength (UCS), Indirect Tensile Strength (ITS) and flexural strength of the different strength ... has a cube compressive strength smaller than 80 MPa and flexural strength smaller than 8 MPa (Domone & Illston 2010; Neville & ... stiffnesses of the respective strength classes in Table 1. These stresses were divided by the flexural strength of the strength ... The high strength of HS-SFRC ensures that the stress level (ratio of tensile stress of flexural strength) remains low, while ...
