A mechanical testing device was developed for testing the behavior of mineral-bonded composites under impact shear loading. The device is based on the well-known double shear specimen configuration and was designed to be used in a gravity split-Hopkinson tension bar (SHTB), enabling shear testing at high loading rates. In this work, results from impact shear testing performed on a normal cementitious matrix (NSM) and strain-hardening cement-based composites (SHCC) tested by means of the new device are presented and discussed. Failure behavior and fracture modes are analyzed using optical measurements and digital image correlation (DIC).
