Rehabilitation of concrete structures using Ultra-High Performance Fibre Reinforced Concrete [PDF]
An original concept is presented for the rehabilitation of concrete structures. The main idea is to use Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) to “harden” those zones where the structure is exposed to severe environmental and high ...

Tensile behavior of Ultra High Performance Hybrid Fiber Reinforced Concrete
Cement and Concrete Composites, 2012Abstract The effects of blending fibers on the tensile behavior of Ultra High Performance Hybrid Fiber Reinforced Concrete (UHP-HFRC) are investigated. Four types of steel macro-fibers (of differing length or geometry) and one type of steel micro-fiber are considered. In producing the specimens, the volume content of the macro-fiber was held at 1.0%,

Confinement of ultra-high-performance fiber reinforced concrete columns
Composite Structures, 2017Abstract This study investigates the axial load response of ultra-high-performance fiber-reinforced concrete (UHPFRC) columns with compressive strengths of 163 and 181 MPa (design strengths of 150 and 180 MPa). The UHPFRC used in this study had 1.5% of hybrid micro-steel fibers (1.0% of 19.5 mm fibers and 0.5% of 16.3 mm fibers) and did not contain ...

Shear resistance of ultra-high-performance fiber-reinforced concrete
Construction and Building Materials, 2017Abstract The shear resistance of ultra-high-performance fiber-reinforced concrete (UHPFRC) was investigated by using a newly proposed shear testing system. UHPFRCs displayed strain-hardening responses, in both shear and tensile testing, accompanied with multiple microcracks.
