MIT startup Allium Engineering’s stainless-clad rebar aims to triple bridge lifespans, cut carbon emissions and resist corrosion, with Caltrans testing underway after a California pilot.

And while badly rusting rebars in a bridge under repair should not be left in place untreated when new concrete is poured, replacing the bars with new steel is not the only acceptable solution.

The concretestrengthening steel bars currently used in bridges are susceptible to corrosion, especially in the "deck," the uppermost portion of the bridge. Rebar embedded in bridgedeck concrete is ...

While many of us might think that concrete structures such as bridges simply stand unaided for decades at a time, the fact is that they require maintenance as often as once every five years. An ...

On a Pennsylvania bridge last month, a prototype robot tied more than 24,000 rebar intersections at a rate of 5.5 seconds each.

TyBot autonomous rebar tying robot that can tie up to 1,000 intersections an hour by autonomously navigating its working area saved 34% in both personnel hours and duration of work on the Koppel ...

STAR CITY, W.Va. -- Samir N. Shoukry works his way from the belly of the bridge to the slippery green rebar of its snow-covered back, talking about the 1,000-foot span over the Monongahela River ...
