This study investigated the effects of steel fibers, surface-reformed by silver and nanosilica coatings, on the static and dynamic pullout behaviors of reactive powder concrete (RPC). To consider the fiber orientation effect, two different inclination angles of 0° and 45° were adopted. The static bo...
