  • Techniques developed to advance concrete construction in frigid environments

    U.S. Army Engineer Research and Development Center (ERDC) researchers have developed Additive Regulated Concrete for Thermally Extreme Conditions – or ARCTEC – to enable the use of commonly available concrete additives as alternative freeze-protection in cold conditions. ARCTEC builds upon pioneering work performed at ERDC over the last several decades, with the goal of improving the user-friendliness, economy and utility of the technology.
  • From Antiquated to Automated: USACE wetland delineation tool helps revolutionize regulatory process

    According to the Environmental Protection Agency, United States has lost more than half of its wetlands since the 1600s, and approximately 35 percent of the world’s wetlands were lost between 1970 and 2015. To protect against further impairment of wetlands and the essential functions they provide, the U.S. established a policy of "no net loss" of wetlands, as well as procedures to ensure responsible management of wetland resources.
