ULTRA-HIGH-PERFORMANCE FIBER- REINFORCED CONCRETE

We accompany you from design to implementation by developing for you an innovative solution, specifying UHPC performances adapted for your project and checking with you the feasibility and economy of the solution

Why Choose UHPFRC For Your Project

Integrated into a repair or strengthening solution, the cost of the UHPFRC is less critical compared to the gains in terms of economic and environmental efficiency (less amount of materials to be used, absence or less amount of reinforcement) and speed of the works on site.

UHPFRC proves to be a material perfectly adapted to the solutions of repair and strengthening of concrete structures, which make it possible to fully exploit its intrinsic performance as well as its flexibility of implementation

This innovative technology has necessitated the development of a new framework for both computational and operational use (manufacturing, implementation and constructive arrangements). The many positive feedbacks resulting from this development now allow its standardization and its specification in the projects.

DIFFERENT TYPE OF APPLICATION

SHOTCRETING IN KHAMBATAKI GHAT TUNNEL BY UHPFRC

Sprayed UHPC Solution

Ideal for the large surface
Thin shell spraying
increased ductility given tension and pressure
enhanced impact strength
improved fatigue behaviour
low propensity for spalling
increased durability

Compared to applying conventional reinforced concrete the application of steel fibre concrete affords clear advantages in conjunction with the concreting method in tunnelling. In particular these relate to increased industrial safety, cost saving for the reinforcing operations as well as making the entire work cycle more straightforward and quicker. The sprayed layer is more homogeneous as no spraying shadows occur on account of spraying through reinforcement. In addition, there is the fact that less overbreak has to be sprayed as the rock contours can be followed better.

Prefabricated UHPC Girder Solution

Ultra-high-performance concrete (UHPFRC) is a newly developed concrete material that provides very high strength and very low permeability. UHPFRC could enable major improvements over ordinary concrete (OC) and high- rformance concrete (HPC) bridges in terms of structural efficiency, durability and cost-effectiveness over the long term.
