The goal for this MUSES exploratory project is to integrate life cycle-based environmental, social and economic design criteria and ECC microstructure tailoring to enhance the sustainability of infrastructure systems. Worldwide construction of concrete infrastructure such as roads, bridges and pipes exceeds 6 billion tons/yr. The resulting impacts are dramatic and include greenhouse gas emissions, land disturbances, air pollution, and construction-related traffic congestion and vehicle damage. Engineered cementitious composites (ECC) are a new class of materials being developed to improve the performance of infrastructure systems. ECC formulations are designed through microstructure tailoring of inputs including matrix (cement and fly ash), fiber (virgin and recycled polymers, and interface elements. While ECC strain capacity is far superior to normal concrete, overall life cycle costs and benefits have not yet been evaluated.Developing these criteria is complex due to widely varying scales of analysis (nanometers in materials science to kilometers in the geological sciences), the long-term nature and consequences of infrastructure systems, and the need to optimize the scheduling of large capital investments. To address this complexity, this research will draw upon a multi-disciplinary team from the University of Michigan's Advanced Civil Engineering Material Research Lab, Center for Sustainable Systems, College of Engineering, School of Public Health, School of Natural Resources and Environment, and Department of Geological Sciences. This project will emphasize student education and research training through two graduate student research assistantships; specialized industrial ecology curriculum; a field component at a local cement manufacturer; a MUSES seminar series; and monthly research team workshops

该MUSE探索性项目的目标是将基于生命周期的环境、社会和经济设计标准与ECC微观结构定制相结合，以增强基础设施系统的可持续性。全世界道路、桥梁和管道等混凝土基础设施的建设超过60亿吨/年。由此产生的影响是巨大的，包括温室气体排放、土地干扰、空气污染以及与建筑相关的交通拥堵和车辆损坏。工程水泥基复合材料(ECC)是为提高基础设施系统性能而开发的一种新型材料。ECC配方是通过对基质(水泥和飞灰)、纤维(原始和可回收聚合物)以及界面元素等投入物的微观结构进行定制而设计的。虽然ECC的应变能力远远优于普通混凝土，但整个生命周期的成本和收益尚未得到评估。制定这些标准是复杂的，因为分析的规模差异很大(从材料科学的纳米到地质科学的千米)，基础设施系统的长期性质和后果，以及优化大型资本投资调度的需要。为了应对这种复杂性，这项研究将利用来自密歇根大学高级土木工程材料研究实验室、可持续系统中心、工程学院、公共卫生学院、自然资源与环境学院和地质科学系的多学科团队。该项目将通过两个研究生研究助学金、专门的工业生态课程、当地一家水泥制造商的现场组件、缪斯系列研讨会和每月研究小组研讨会来强调学生的教育和研究培训。
