VLIV HOMOGENITY ROZPTÝLENÍ DRÁTKŮ NA NOSNOST DESEK Z UHPC

Original language description

Ultra-High Performance Fibre Reinforced Concrete is fine grained cementitious composite material from the wide range of Ultra-High Performance Concrete. Uniform designation and classification does not exist for 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 at real constructions and 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 bottom of the formwork. The paper describes not only bending tests on the slabs but it describes also a method for checking the steel fibre homogeneity and its impact on load bearing capacity of the slabs.
