Composite fibres set to bring change to bridge building technology
Materials science has quickly become a much broader field than it was, even 30 or 40 years ago.
Then nanotechnology came along and opened up a whole new field — engineering materials at a molecular level. Nanoscientists became the new stars of material science, but those dealing in more traditional aspects of material science never stopped looking for specialized concrete mixes, for example, or steels engineered for specific tasks.
Now a young Swedish scientist has come up with a new idea in bridge building.
Peter Harryson said that with new bridge-building materials, industrial production methods and an efficient construction process, it will be possible to start using a bridge just two weeks after construction begins.
In fact, he said, it could be done now, were it not for the cost.
