This Biocomplexity in the Environment - Materials Use: Science, Engineering and Society (MUSES) project brings together researchers from three countries and seven disciplines to create models and evaluate new materials aimed at reducing the environmental impact of concrete used in large civil infrastructures. Global production of concrete drives huge flows of material between natural and human systems. The shear magnitude of this material flow, which exceeds 12 billion tons each year, causes significant societal impacts. For example, concrete-based infrastructure projects require major investments of public capital, trigger enormous greenhouse gas emissions from cement production, and lead to construction-related traffic congestion resulting in pollution and lost productivity. Developments of new materials to supplement or replace concrete to improve the performance characteristics typically do not address the broad economic, environmental, and social consequences. This project will address this shortcoming by developing a novel framework for sustainable design that integrates microstructure tailoring with life cycle analysis. The project explores engineered cementitious composites (ECC) both from a technical design standpoint and from the health, economics, and policy perspectives. The project includes micro-scale research on the development of ECC, macro-scale application of ECC to bridge decks, roadways, and pipes, incorporation of recycled materials, measurement of life-cycle impacts, and investigation at different geographic scopes. This work encompasses multi-disciplinary perspectives including civil and materials engineering, geology, environmental health sciences, industrial ecology, environmental economics, and public policy. Among the issues to be explored are the impacts of sourcing alternatives (superquarries vs. smaller mines) and location of infrastructure projects (urban vs. rural, and U.S. vs. China). Given the inherent design complexity, researchers will incorporate uncertainty and sensitivity analysis in their quantitative models to ensure that results are sufficiently robust to support effective decision-making in the adoption of new materials. The University of Michigan team will collaborate with researchers at the Tohoku University in Japan, who will investigate the use of CO2 hardening process on the ECC mixes; researchers at Tsinghua University in China who will use the life cycle model to assess sustainability performance of infrastructure systems in China, and Stanford University. Educational outreach will be facilitated through a web-based educational resource compendium, as well as through a series of workshops involving the global partners. It is expected that this MUSES research will have a significant impact on materials use in large, civil infrastructures and will provide tools that will accelerate the adoption of new materials and material substitutions that lower the environmental impact over their whole life cycle.

环境中的生物复杂性-材料使用：科学，工程和社会（MUSES）项目汇集了来自三个国家和七个学科的研究人员，旨在创建模型并评估旨在减少大型民用基础设施中使用的混凝土对环境影响的新材料。混凝土的全球生产推动了自然系统和人类系统之间巨大的材料流动。这种物质流的剪切量每年超过120亿吨，对社会产生重大影响。例如，以混凝土为基础的基础设施项目需要大量公共资本投资，在水泥生产过程中会产生大量温室气体排放，并导致与建筑相关的交通拥堵，从而造成污染和生产力损失。新材料的发展，以补充或取代混凝土，以提高性能特征通常不解决广泛的经济，环境和社会后果。该项目将通过开发一种新的可持续设计框架来解决这一缺点，该框架将微观结构定制与生命周期分析相结合。该项目从技术设计角度、健康、经济和政策角度探索工程胶凝复合材料（ECC）。该项目包括微观尺度上的ECC发展研究，宏观尺度上的ECC在桥面、道路和管道上的应用，回收材料的结合，生命周期影响的测量，以及不同地理范围的调查。这项工作涵盖了多学科的观点，包括土木和材料工程、地质学、环境健康科学、工业生态学、环境经济学和公共政策。需要探讨的问题包括采购替代方案的影响（超级采石场vs小型矿山）和基础设施项目的位置（城市vs农村，美国vs中国）。考虑到固有的设计复杂性，研究人员将在他们的定量模型中纳入不确定性和敏感性分析，以确保结果足够稳健，以支持采用新材料的有效决策。密歇根大学的研究小组将与日本东北大学的研究人员合作，后者将研究在ECC混合料上使用二氧化碳硬化过程；中国清华大学的研究人员，他们将使用生命周期模型来评估中国基础设施系统的可持续性表现，以及斯坦福大学。将通过一个基于网络的教育资源纲要以及由全球伙伴参加的一系列讲习班，促进教育外展。预计这项muse研究将对大型民用基础设施的材料使用产生重大影响，并将提供加速采用新材料和材料替代的工具，从而降低其整个生命周期对环境的影响。
