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.

波特兰混凝土是建筑环境中无处不在的元素，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水泥制造材料，其生产会导致 4- 温室气体 (GHG) 排放。全球能源相关二氧化碳 (CO2) 排放量的 8% 需要在施工期间和混凝土的整个生命周期中减少二氧化碳排放量。混凝土进步网络 (CAN) 是一个产学合作研究阶段。 I 中心 (IUCRC) 由威斯康星大学密尔沃基分校和俄勒冈州立大学建立，致力于降低混凝土的全球变暖潜势 (GWP)，同时提高混凝土的长期耐久性，从而实现显着的经济和社会效益。实施纳米技术进步、可回收性、数字制造、多尺度建模、人工智能和先进的测试技术将用于快速跟踪前沿概念在这个经常依赖旧技术突破的关键工业领域的实施。混凝土领域CAN 中心旨在开发具有降低 GWP 的创新混凝土混合物，同时建立量化 GWP 和成员性能的方法。因此，CAN 活动对美国经济具有重要战略意义，因为它们将为国家日益恶化的基础设施提供长期解决方案，并满足交通和建筑的需求。 CAN大学威斯康星州-密尔沃基工厂拥有与纳米技术在混凝土中应用相关的独特专业知识和能力，可转化为纳米工程复合材料、超高性能混凝土、光催化混凝土、智能传感器嵌入式结构、创新的开发和有效使用在副产品利用、辅助胶凝材料的应用、碳减排和封存、数字化制造以及延长使用寿命方面，此外，经过 ISO 17025 认证的结构测试设施还提供了独特的能力。 CAN 研究人员利用先进的分析和操纵从纳米到介观尺度的化学相互作用，扩大并验证实验室开发的概念，旨在开发现代技术和方法，从而生产出更高效、更快速部署且成本更低的混凝土。中心的研究工作将通过使用基于模型的预测和验证代替传统的实验方法来实现具体科学的突破，从而加快技术从概念到实施的步伐最后，计划提供培训计划来帮助做好准备。下一代工程师，同时还提供信息更新该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
