Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges
The forms of U-shaped UHPFRC beams have not been investigated for the highway footbridge. Compared with the traditional section forms, the U-shaped UHPFRC beams can reduce the material consumption under the condition of providing the same bearing ...

Mechanical and fracture properties of a self-compacting version of CARDIFRC Mix II [PDF]
CARDIFRC is the trade name of two main groups of ultra-high performance fibre-reinforced concrete mixes – Mixes I and II – differing primarily in the maximum size of quartz sand used (0.6 mm in Mix I, and 2 mm in Mix II). In this paper, the conversion of

Micro X-ray computed tomography image-based two-scale homogenisation of ultra high performance fibre reinforced concrete [PDF]
A two-scale analytical-numerical homogenisation approach is developed to predict effective elastic properties of ultra high performance fibre reinforced concrete considering distribution of pore sizes acquired from 3D micro X-ray computed tomography ...
