Abstract: The article at hand presents the results of a series of short-time dynamic and quasi-static experiments on a high-strength SHCC made of cement-based matrix and high-density polyethylene fibres (HDPE). The dynamic tension tests were performed using the Split-Hopkinson bar in the spallation configuration at strain rates of approximately 150 s-1. The responses of the material under dynamic and quasi-static tensile loadings are compared in terms of tensile strength as well as multiple crack formation and condition of fracture surfaces. The strain rate dependent changes of the fibre-matrix interface properties as deduced from the state of the failure surfaces are confirmed and quantified by single fibre pull-out tests.
