  • Making it up with CRREL's machine shop

    Whether you’re a hobbyist at home or a researcher at the U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL), not having one special piece to finish a project and that isn’t readily available is universal. The engineers, researchers, and scientists at CRREL need only ask Chris Donnelly, a CRREL engineering technician and machine shop manager, to make them the part they require.

  • ERDC researchers investigate how climate change impacts permafrost

    Permafrost is found beneath nearly 85 percent of Alaska. While it is typically very strong, as the ice in the permafrost begins to warm, it weakens, and foundations built upon it may begin to fail. CRREL researchers at the Permafrost Tunnel Research Facility are working to address challenges with building on permafrost.

  • ERDC synergizes at the Army Engineer Association industry exhibit

    From April 24 to 28, a team of U.S. Army Engineer Research and Development Center (ERDC) representatives attended the exhibit portion of the Army Engineer Association (AEA) Regimental Week at Fort Leonard Wood, Missouri.

  • ERDC Engineer Studies, Dances on Ice

    Passion is a key component to success, whether that be for work, a hobby or a sport. In the workplace, passion has motivated Marin Blaisdell to be a successful materials engineer for the U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory (CRREL). But a separate passion has driven her to compete in figure skating at the national level. Blaisdell knows the importance of dedication and precision, whether she is in Anchorage, Alaska, performing CRREL strength tests on snow patches used for rapid airfield crater damage repair, or perfecting a double salchow-single loop-double loop; she knows it takes perseverance to achieve her best.

  • New Technology Successfully Demonstrated During Arctic Exercise

    During a multi-service exercise, the U.S. Army Engineer Research and Development Center (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) successfully demonstrated a groundbreaking technology to detect airborne targets.

  • Making Waves: ERDC studies oil spill cleanup techniques

    In the event of an oil spill in the ocean, such as an oil tanker tipping over, its container getting breached or an oil rig’s pipeline leaking, immediate response for cleanup is needed. However, at times, it can be difficult to determine the best means of effective oil-spill cleanup.

  • CRREL tests new ways to measure smoke density

    CRREL partners with the U.S. Coast Guard's Research and Development Center and the Environmental Protection Agency to test an aerial drone to determine how effective the device is for measuring air quality and environmental impact of burning oil on water. The aerial drone is a new means of capturing these measurements, and CRREL is one of the few federal agencies with the knowledge, permissions, licenses, and facilities to accommodate in situ burns.

  • A Cold Start: ERDC tests Stryker batteries in frigid temps

    Many people living in northern regions of the United States have experienced getting in a car on a cold, winter morning, turning the key in the ignition and having the engine starter sputter, but not start. This relatable inconvenience is one that many people have dealt with. However, for U.S. military service members called to action in regions such as northern Alaska, there is no time to deal with a vehicle that won’t start in the extreme cold temperatures. This is a dilemma that engineers like Kathryn Trubac, a research general engineer for the U.S. Army Engineer Research and Development Center (ERDC) Cold Regions Research and Engineering Laboratory (CRREL), are working to resolve.

  • Cold Regions Laboratory celebrates Engineer Day by recognizing personnel

    The U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, New Hampshire, celebrated Engineer Day July 15.

  • Long-Term Durability of Cold Weather Concrete: Phase II

    Abstract: Recent laboratory results confirm that it is possible to protect concrete from freezing solely using chemical admixtures and indicate that the amount of admixture required may be significantly less than previously recommended. Researchers have also verified that admixture-based freeze protection can produce concrete that is durable to winter exposure for a minimum of 20 years, through petrographic examination of core specimens obtained from past field demonstrations. Freeze protection for concrete using chemical admixtures alone has been an area of active research for 3 decades; however, the most recent methodology recommends very high addition rates of accelerating and corrosion inhibiting admixtures, which result in significant challenges, including slump loss, rapid setting, and potentially excessive temperature rise. As part of a laboratory study, researchers systematically varied the dosage of freeze protection admixtures used in concrete cured in a 23 °F environment. Preliminary findings indicate that a 50% reduction in admixture dose maintained adequate freeze protection and resulted in compressive strengths exceeding those of room-temperature controls at 7 and 28 days. The combination of improved handling, reduced cost, and verified durability associated with the use of admixtures for freeze protection makes a compelling case for broader adoption of this technique in winter operations
