Mechanical performance and cost correlation of Ultra High Performance Fiber Reinforced Concrete (UHPFRC)

, 2016
Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is a material which is characterized by enhanced mechanical properties. The properties of the material are highly depended on the composition of the mix and the curing regimes.

Structural performance of ultra‐high‐performance fiber‐reinforced concrete beams [PDF]

Structural Concrete, 2017
Ultra‐high‐performance fiber‐reinforced concrete (UHPFRC) is a relatively new construction material. In comparison with conventional high‐strength concrete, UHPFRC does not usually contain coarse aggregates larger than 6–7 mm in size. This paper presents the outcomes of an experimental study of UHPFRC beams subjected to four‐point loading.
