A spin-off from the state-owned VTT Technical Research Centre recently secured funding to commercialize its system of mineralizing carbon dioxide while curing precast concrete elements at atmospheric pressure.
When the city of Lenexa, Kan., this spring opted to move forward with a test pilot of “smart pavements,” it represented a vital step forward for electric vehicles.
Beauty and beastly strength: Concrete made by Fort Miller Group, which precast the giant concrete flowerpot-like structures for Manhattan’s Little Island park on the Hudson River, boasts this traditionally unlikely combination.
American Concrete Institute says its first-ever initiative to develop a precast standard is not related to an article in Concrete International that sounds the alarm about the potential for brittle failures of non-code-compliant precast, prestressed-concrete double-T parking decks, with flanges reinforced with a high-strength polymer-coated carbon-fiber grid product, called C-Grid.
A new bridge connecting Portsmouth, N.H., and Kittery, Maine, features what engineers believe is the first-ever use of precast-concrete segmental towers on a vertical-lift bridge.
A horizontally curved, precast- concrete, trapezoidal type of box-girder design that shaved some $9 million off an interchange project in Orlando, Fla., is attracting growing interest from the bridge engineering industry.
