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 Oregon State site is focused on the development of approaches to improve concrete performance predictions specifically as it relates to durability, by-product utilization, and a reduced carbon footprint. Novel experimental measurement techniques and computational tools will be showcased that can provide value to the industry. Oregon State will focus primarily on four primary research thrust areas: 1) the increased use of ‘off-spec’, natural, and ‘industrial by-product’ supplementary cementitious materials to reduce the global warming potential of concrete, 2) carbon reduction, sequestration, and use of carbonatable binders, 3) molecular and thermodynamic modeling and 4) concrete durability, longevity, and service life modeling. It is anticipated that work will focus on the development of mixture proportioning tools that result in mixtures with low GWP as well as approaches that better consider the service life emissions of concrete. Advanced experimental techniques like neutron radiography are planned to assess the influence of fluid transport and carbonation on concrete development and performance. Additionally, work will be performed to quantify the durability of concrete which will likely include updates to the service life prediction of concrete exposed to acid and the role of commercial additives in reducing transport and acid damage. 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。混凝土是使用最广泛的制造材料，其生产也是温室气体排放的一个因素。 水泥生产导致全球能源相关二氧化碳（CO2）排放量的4-8%。 有必要在施工期间和混凝土的整个寿命期间减少CO2排放。 混凝土进步网络（CAN）是由威斯康星大学密尔沃基分校和俄勒冈州州立大学建立的一个产学研合作研究第一阶段中心（IUCRC），专注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尖端概念在这一关键工业领域的实施，该领域经常依赖旧技术。通过使用基于模型的预测和验证，结合实验方法，可以实现具体领域的突破，从而加快技术转让从概念到实施的步伐。 CAN中心旨在开发具有降低GWP的创新混凝土混合物，同时为成员公司建立量化GWP和性能的方法，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战略重要性，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，并满足对运输和建筑物的需求。CAN俄勒冈州的网站专注于开发方法，以提高混凝土性能预测，特别是因为它涉及耐久性，副产品利用率和减少碳足迹。新的实验测量技术和计算工具将被展示，可以为行业提供价值。俄勒冈州将主要集中在四个主要的研究重点领域：1）增加使用“不合格”，天然和“工业副产品”的补充胶凝材料，以减少混凝土的全球变暖潜力，2）碳减排，封存和使用碳酸化粘合剂，3）分子和热力学建模和4）混凝土耐久性，寿命和使用寿命建模。 预计工作将侧重于开发混合物配比工具，以产生低全球升温潜能值的混合物，以及更好地考虑混凝土使用寿命排放的方法。 先进的实验技术，如中子射线照相，计划评估流体输送和碳化对混凝土的发展和性能的影响。 此外，还将对混凝土的耐久性进行量化，其中可能包括对暴露于酸的混凝土的使用寿命预测的更新，以及商业添加剂在减少运输和酸损害方面的作用。 最后，培训计划旨在帮助下一代工程师做好准备，同时也为从业者提供最新信息。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
