• Researchers look for a better way to build bridges

    Canadian researchers look for ways to make bridges sturdier; one project looks at the use of advanced fiber-reinforced polymers (FRPs) to protect critical concrete infrastructure against extreme shocks; the second study involves the use of ultra high-performance concrete (UHPC) to build long-life, lightweight and cost-effective bridges

  • Imperial College London awarded £4.9 million to research cloaking properties of metamaterials

    Metamaterials have properties that could lead to the development of invisibility “cloaking” devices, sensitive security sensors, and flat lenses that can be used to image objects much smaller than the wavelength of light; Imperial College London receives a £4.9 million grant to do research on metamaterials

  • Downtown airport boasts a new runway safety system

    Safety barriers made of new type of absorbing concrete are installed at a Kansas City airport; the barriers are made of concrete blocks which collapse to absorb the energy of the airplane while minimizing the damage to the aircraft and allowing the aircraft to be slowed without hurting passengers

  • New material makes buildings more fire resistant

    New material, called “liquid granite,” is fire resistant to temperatures in excess of 1,100oC; it reduces the fire risk in buildings because, unlike concrete, it does not explode at high temperatures

  • Carbon fibers improve blast, impact resistance of conventional reinforced concrete

    Researchers find that adding longer carbon fibers to conventional reinforced concrete significantly improves a structure’s ability to withstand blasts, hurricanes, and other natural disasters

  • New Bay Bridge span designed to endure major quake

    Twenty years ago a 250-ton section of the Bay Bridge fell into the water as a result of a 6.9 magnitude earthquake; the new bridge design will be able to withstand the largest plausible earthquake to occur within a 1,500-year period

  • Indonesian experts: Dense soil, light materials vital for sturdier buildings

    In the wake of last Wednesday’s devastating earthquake in Indonesia, experts call for more care in choosing sites for new buildings and communities; key factor: the stability of the soil; “If you build the foundation 20 to 30 meters deep, then you need very dense soil,” an expert said

  • U.S. government eyes University of Maine's bridge technology

    Researchers at the University of Maine developed a “bridge-in-a-backpack” technology — so called because of its light weight and the portability of its components; the bridge uses carbon-fiber tubes that are inflated, shaped into arches, and infused with resin before being moved into place

  • All-titanium campus bridge show way for defense industry

    University of Akron, Defense Metals Technology Center co-sponsor design contest for titanium pedestrian bridge on university’s campus; titanium is a strong, lightweight, virtually corrosion-proof (but expensive) metal; a high-profile venture demonstrating titanium’s feasibility in commercial infrastructure projects could spark greater demand and open new markets for titanium
    ‘Avant-garde’ all-titanium span could spur other projects - and cut Pentagon’s costs

  • New titanium alloys offer better IED protection

    Titanium deforms and retains damage from strong impacts and fast applied forces — such compression on the metal can happen when it is hit by bullets or explosives; metallurgy theory provides a greater understanding of the material at the atomic scale — an understanding which will lead to the production of more resilient titanium

  • Scientists develop self-healing surface material

    The human skin, when scratched or cut, heals quickly, in most cases leaving no trace of a scar after just a few days; German scientists develop surface material with similar qualities

  • Glass fibers can make a building sturdier

    Conventional means to reinforce concrete involve the use of steel bars; the use of fiber reinforced polymer (FRP) is emerging as a valuable option, owing to its natural resistance to corrosion, its high strength, light weight, transparency to electrical and magnetic fields and ease of manufacturing and installment

  • New fire-resistant coating materials developed

    Aussie researchers develop HIPS — Hybrid Inorganic Polymer System — coating; it can withstand temperatures of more than 1,000°C compared to current commercial coatings used on building materials and structures, which break down between 150-250°C

  • New bullet proof vests will be made from cement

    University of Leeds researchers say that vests made of cement would offer cost-effective level of protection for many people at risk; it should be good enough for people like security guards, reporters and aid workers who are worried about the odd pot shot being taken at them

  • Using cloth to protect military vehicles from RPGs

    British company shows a newly developed textile which is strong enough to protect battle-field vehicles from RPGs
