Abstract
The article presents examples of the use of ultra-high performance fiber reinforced concrete for load-bearing structures in Russia. Using this material with limits of compressive strength 150 MPa, flexural tensile strength 21 MPa, tensile strength 8.5 MPa, external post-tensioned structures of bridges and tanks are made instead of common solution with the steel anchors. Full-scale tests of anchors were carried out, which did not reveal signs of deformations and destruction of elements during the tension of strands, at the level of design and ultimate loads - before strands rupture. It was concluded that it is advisable to replace steel anchors with anchors from the material, which, with high strength characteristics, has ultra-low permeability and high frost resistance corresponding to the F21000 class. The estimated economic effect of such a replacement is determined by the reduced cost of these elements of structures made of ultra-high performance fiber reinforced concrete in comparison with steel.
