Some professors at Montreal's Ecole Polytechnique are hoping they'll get a chance to pitch their super-concrete idea for the new Champlain Bridge.
They say the ultra-high performance fibre-reinforced concrete the school's lab has been experimenting with would be perfect for the project.
The compound contains steel fibres that prevent cracks and therefore cut down on the damaging effects of water infiltration and corrosion.
They say the substance has a life span of up to a hundred years - but to ensure this kind of longevity for the Champlain's replacement, authorities would have to be prepared to pay now for the more expensive super-concrete.
A two-day conference on the creation and uses of fibre-reinforced concrete opens today in Montreal.
