New concrete formula for long-lasting roads, bridges
US researchers have developed an ultra high-performance concrete formula which is stronger and more durable than conventional versions
and could lead to roads and bridges that last longer and are cost effective. Ultra high-performance concrete, or UHPC, has been on the market for a while under a small handful of brand names, said researchers from the University of Michigan in the US. However, high prices have kept it out of widespread use, they said.
