Portland cement concrete is a ubiquitous element of the built environment and is a crucial component of building and infrastructure development worldwide. The production of concrete, the most widely used manufactured material, is a contributor to greenhouse gas (GHG) emissions. The production of cement results in 4-8% of global energy-related carbon dioxide (CO2) emissions. There is a need to reduce the CO2 emissions both during construction and throughout the life of the concrete. The Concrete Advancement Network (CAN), an Industry-University Cooperative Research Phase I Center (IUCRC) established by the University of Wisconsin-Milwaukee and Oregon State University, focuses on reducing the global warming potential (GWP) of concrete while improving the long-term durability of concrete thereby enabling significant economic and societal benefits. CAN focuses on implementing nanotechnology advancements, recyclability, digital manufacturing, multi-scale modeling, artificial intelligence, and advanced testing techniques will be used to fast-track the implementation of cutting-edge concepts into this key industrial sector, which frequently relies on older technology. Breakthroughs in the concrete field can be achieved using model-based prediction and verification combined with experimental methods, thereby advancing the pace of technology transfer from concept to implementation. The CAN center aims to develop innovative concrete mixtures with reduced GWP while establishing methods to quantify the GWP and performance for member companies while training a diverse and skilled science and engineering workforce for the industry at large. Thus, CAN activities are strategically important to the U.S. economy because they will provide long-term solutions for the nation’s deteriorating infrastructure and meet the demand for transportation and buildings.The CAN University of Wisconsin-Milwaukee site has unique expertise and capabilities related to the use of nanotechnology in concrete, which are translated to the development and effective use of nano-engineered composites, ultra-high-performance concrete, photocatalytic concrete, smart sensor-embedded construction, innovations in by-product utilization, application of supplementary cementitious materials, carbon reduction and sequestration, digital manufacturing, and the extension of service life. In addition, the ISO 17025-certified structural testing facility provides a unique capability to scale-up and verify the concepts developed in the lab. Using advanced analysis and manipulating chemical interactions from nano to mesoscale, CAN researchers aim to develop modern technologies and methods that will result in concrete that is more efficient, more rapidly deployable, and much less dependent upon natural resources. Center research efforts will enable breakthroughs in concrete science by using model-based prediction and verification in lieu of traditional experimental methods, thereby advancing the pace of technology transfer from concept to implementation. Finally, training programs are planned to help prepare the next generation of engineers while also providing information updates for practitioners.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

波特兰水泥混凝土是建筑环境中无处不在的元素，也是全球建筑和基础设施发展的重要组成部分。混凝土是最广泛使用的制造材料，是温室气体(GHG)排放的贡献者。水泥的生产导致了全球能源相关二氧化碳(CO2)排放量的4%-8%。在施工期间和混凝土的整个使用寿命期间都需要减少二氧化碳排放。混凝土发展网络(CAN)是由威斯康星大学密尔沃基分校和俄勒冈州立大学建立的工业-大学合作研究第一阶段中心(IUCRC)，其重点是降低混凝土的全球变暖潜力(GWP)，同时提高混凝土的长期耐久性，从而产生显著的经济和社会效益。CAN专注于实施纳米技术进步，可回收性，数字化制造，多尺度建模，人工智能，和先进的测试技术将被用来快速跟踪尖端概念在这个经常依赖旧技术的关键工业部门的实施。基于模型的预测和验证与实验方法相结合，可以在具体领域实现突破，从而加快技术转移从概念到实施的步伐。CAN中心的目标是开发降低全球变暖潜能值的创新混凝土混合料，同时为成员公司建立量化全球变暖潜能值和表现的方法，同时为整个行业培训多样化和熟练的科学和工程劳动力。因此，CAN活动对美国经济具有重要的战略意义，因为它们将为美国日益恶化的基础设施提供长期解决方案，并满足交通和建筑需求。威斯康星大学密尔沃基分校的CAN工厂拥有与在混凝土中使用纳米技术相关的独特专业知识和能力，这些专业知识和能力体现在纳米工程复合材料、超高性能混凝土、光催化混凝土、智能传感器嵌入建筑、副产品利用创新、补充胶凝材料的应用、碳减排和封存、数字制造和延长使用寿命方面。此外，国际标准化组织17025认证的结构测试设施提供了独特的能力来扩大和验证在实验室中开发的概念。利用先进的分析和操纵从纳米到中尺度的化学相互作用，CAN研究人员的目标是开发现代技术和方法，从而使混凝土更高效、更快速地部署，并大大减少对自然资源的依赖。中心的研究工作将使具体科学取得突破，使用基于模型的预测和验证来取代传统的实验方法，从而加快技术转移从概念到实施的步伐。最后，计划开展培训计划，以帮助培养下一代工程师，同时为实践者提供最新信息。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
