This standard specifies the terms and definitions of high ductility fiber-reinforced cement-based composite materials, specimen preparation methods, cube compressive strength, axial compressive strength, static compressive elastic modulus, flexural strength, and first crack tensile strength. , ultimate tensile strength, ultimate elongation, average crack spacing and average crack width test methods. This standard applies to precast and cast-in-place high-ductility fiber-reinforced cement-based composite materials.
