Due to the increased concern of public safety in recent years, blast resistance of infrastructures has become an emerging research focus in the cement and concrete industry. Ultra High Performance Concrete (UHPC) with fiber reinforcement usually possesses compressive strengths greater than 200 MPa, which makes them promising candidates for blast-resistant building materials. In the current project, two UHPC materials, Ductal and ERDC-M, were subject to projectile penetration testing. The microstructural evolution due to projectile impact was examined via scanning electron microscopy and X-ray diffraction. Possible phase changes were observed in the impact volume, which was likely a result of the high temperature and high pressure induced by the impact.
