  • The details behind Chan-Moon Chung's self-healing concrete
    Chan-Moon Chung of Yonsei University in South Korea used a chemical approach to create self-healing concrete. He mixed methacryloxypropyl-terminated polydimethylsiloxane and benzoin isobutyl ether into small capsules made of urea and formaldehyde to keep the chemical mixture safe from sunlight and mixed them into the concrete. This article details how the capsules rupture and how their contents heals the cracks, providing resistance to water.

  • Fla. eyes "less-expensive" design for outdated I-395 bridge
    Florida is exploring a "less-expensive" design to replace an obsolete overpass on Interstate 395 in Miami. The "segmental box" could be an alternative to the suspension bridge called the Wishbone Arch that was selected by the citizens' committee last month. The alternative option could drop the cost for the new highway by about $114 million. The 300-foot-long segmental-box option would be braced by columns, unlike the Wishbone Arch. Not all are happy with the "stripped-down concrete bridge" design. The Miami Herald (free registration) (3/4) LinkedInFacebookTwitterEmail this Story

  • Transparency is better than cool, says Qualtrics CEO

"We want to be transparent because we want to encourage our people to have all the information to keep them focused on what really matters -- our objectives and how they're going to contribute," Smith says.
