Response and Damage Assessment of Ultra High Performance Fiber Reinforced Concrete Subjected to Deformable and Non-deformable Projectile Impact

Popis výsledku v původním jazyce

The aim of this paper is to describe a response and damage of concrete slabs made of Ultra High Performance Fiber Reinforced Concrete (UHPFRC) subjected to deformable and non-deformable projectile impact. UHPFRC is currently one of the biggest challenging issues in modern concrete technology. The UHPFRC represents a concrete with improved durability and strength, which is significantly higher than in conventional normal strength concrete. This may results in reduced cross-sections and as a consequence smaller dead-load of the structure. The uniaxial compressive cylinder strength of UHPFRC used in this study exceeded 130 MPa. Several UHPFRC mixtures with different content of fibers were subjected to projectile impact. The ogive nose shape projectile weighed 8.04 grams and its average velocity was determined to be 710 m/s. It was found that specimens containing 2% of fibers by volume have optimal resistance against deformable projectiles impact. Slabs containing 2% of fibers were further
