Abstract: Ultra-high performance fiber reinforced concrete is a composite material with a high cement
and silica fume content, a low water-binder ratio, and aggregates smaller than 4 mm. It has
outstanding material characteristics such as self-consolidating workability, very high
mechanical properties and low permeability, which results in excellent environmental
resistance. Typical strengths are 100 to 200 MPa in uniaxial compression and 6 to 15 MPa in
uniaxial tension. Moreover, these materials exhibit strain hardening under tension and a
significant energy absorption capacity. In addition, the author describes a formulation process
for ultra-high performance fiber reinforced concrete that has been developed without using
heat treatment, pressure, or a special mixer. Only ordinary materials available commercially
in the Czech Republic were utilized throughout the material design process.
