Vliv distribuce ocelových vláken na ohybovou únosnost desek vyrobených z UHPFRC

Popis výsledku v původním jazyce

UHPFRC is increasingly being used around the world. Ultra-High Performance Steel Fibre Reinforced Concrete is fine grained cementitious composite material from the wide range of Ultra-High Performance Concrete. Uniform designation and classification doesnot exist for this type of material. The compressive strength is one of the significant parameter for UHPFRC materials but even that is not uniformly defined too. Compressive strength greater than 150 MPa can generally characterizes this type of material. UHPC is used more widely around the world than in the Czech Republic. The development of this type of material is associated with a number of technical and technological problems that need to be solved before using this material at real constructionsand real parts of structures. Homogeneity of the steel fibre distribution at cross section is one of those problems. Mechanical properties, especially flexural bending strength, could be negatively affected by segregation of fibres to the
