An Assessment of the Steel Fibre Distribution to Load Bearing Capacity of Lost Shuttering Slabs Made from UHPFRC

Popis výsledku v původním jazyce

The lost shuttering slabs investigated in this paper were made from relatively new UHPFRC cementitious composite materials reinforced by steel fibres. The slabs were used for reconstructing a narrowed steel-concrete bridge. The slabs were used as a permanent formwork. Sets of material tests were made while the mixture recipe was under development and then tests of the manufactured precast elements were carried out. The mixture recipe was optimized for the mechanical properties. But mixture recipe was also optimized for homogeneity of the steel fibre distribution in the cross section. The steel fibre distribution has a significant impact on the mechanical properties of lost shuttering slabs, especially on the load-bearing capacity at bending. This paperdescribes not only the mechanical tests on the slabs (tension strength in bending), but also methods for checking the homogeneity of the steel fibre distribution the cross section for hardened UHPFRC.
