Ordinary Portland cement (OPC) is by far the world’s most widely used manufactured material and is central to sustainable built environments, yet its manufacturing demands high energy, emits a large amount of CO2, and overconsumes natural resources, and hence is not eco-friendly. This multidisciplinary Future EcoManufacturing research grant seeks to create future eco-friendly manufacturing of next-generation greener cements by simultaneously utilizing the CO2 equivalent (CO2e) emissions from OPC manufacturing and innovatively upcycling the wastes generated from mining and refining industries as feedstocks. The approach is inspired by and further engineers two geological processes, namely: (1) subaerial exothermic rock weathering for carbon mineralization, and (2) subsurface diagenetic alteration of mineral deposits under low-temperature, hydrothermal conditions to form rocks at a massive scale. The targeted product is a new class of silicate-cemented carbonates (iCem) to be manufactured for the first time by transforming Ca/Mg-leached polymeric silicates from waste feedstocks as cementing agents, promoted by silanization to prevent their folding and aggregation, to bond the precipitated carbonates that permanently store gaseous CO2 in solid minerals as value-added products. This project is designed not only to generate the fundamental science on the polymeric silicate-cemented iCem and develop knowledge on future manufacturing of iCem, but also to tackle multiple pressing global challenges, including CO2 emission, climate change, and industrial waste upcycling. The project aims to contribute to advancing sustainability, environmental protection, and circular economy, thereby generating significant impacts on the environment and human society at multiple scales and dimensions. The project aims to have a transformative impact on traditional OPC manufacturing and mining/refining processes. It intends to create: (1) a new manufacturing pathway for next-generation, eco-friendly cementitious materials (iCem) that simultaneously maximizes carbonation and improves iCem’s properties; (2) new science through which polymeric silicate structures are preserved by silanization as cementing and scaffolding constituents to strengthen iCem; (3) innovative multifunctional use of amine silanes to enhance CO2 adsorption and carbonation, bridge different silicate structures, and regulate nano-sized carbonate precipitation; (4) novel combination of carbonation and cold sintering to create eco-friendly manufacturing processes; and (5) eco-friendly technologies for upcycling mine wastes towards a more circular economy, addressing pressing techno-socio-economic challenges of the massive mine wastes anticipated from worldwide adoption of electric vehicles. Concurrent education, workforce development, and outreach activities aligned and accompanied with the research plan are jointly conducted among five collaborating academic institutions (with two from EPSCoR states, one being an HBCU/MSI), to train a diverse, next-generation workforce with multidisciplinary skills in future manufacturing of sustainable cementitious materials (a field that critically needs new workforce), through research training and mentoring, curricula development, short courses and workshops, and various outreach activities at local community colleges, vocational, middle, and high schools. This Future Manufacturing award is supported by the Divisions of Chemical, Bioengineering, Environmental and Transport Systems (CBET) and Civil, Mechanical and Manufacturing Innovation (CMMI).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.

普通的波特兰水泥（OPC）是迄今为止世界上最广泛的制造材料，对于可持续建筑环境而言是核心，但是其制造业需要高能源，发出大量的二氧化碳，并且过度会自然资源，因此不友好。这项跨学科的未来生态制造研究赠款旨在通过仅使用OPC制造业的CO2等效（CO2E）排放来创建下一代绿色水泥的未来生态友好制造，并创新地升级了从采矿和精炼行业作为原料产生的废物。该方法的启发是受到进一步工程师的启发，即两个地质过程：（1）碳矿化的亚赛下放热岩石风化，（2）（2）在低温，水热条件下以大规模形成岩石的地下矿物沉积物的地下偏置静电改变。有针对性的产品是一种新的硅酮污染碳酸盐（ICEM）（ICEM），首次通过将Ca/mg覆盖的聚合物硅酮从废物原料中转换为胶结剂，通过硅化剂来促进，以防止其折叠和汇总，将永久的贵碳酸盐粘合到固体co2中，以将co2储存在固体co2中，将其存储在固体矿物质的产品中，并将其作为价值 - 固定产品固定。该项目不仅旨在在聚合硅胶胶结的ICEM上产生基本科学，并在ICEM的未来制造中发展知识，还旨在应对多种紧迫的全球挑战，包括CO2排放，气候变化和工业废物升级。该项目旨在为推进可持续性，环境保护和循环经济做出贡献，从而在多个规模和维度上对环境和人类社会产生重大影响。该项目旨在对传统的OPC制造和采矿/炼油过程产生变革性的影响。它打算创建：（1）一种新的制造途径，用于下一代，环保的水泥材料（ICEM），该材料（ICEM）简单地最大化了碳化并改善了ICEM的特性； （2）通过硅烷化将聚合物有机硅结构保存为胶结和脚手架构成增强ICEM的新科学； （3）胺硅烷的创新多功能使用以增强二氧化碳吸附和碳化，桥梁不同的硅酮结构并调节纳米尺寸的碳酸盐沉淀； （4）碳酸化和冷烧结的新型组合，以创造生态友好的制造工艺； （5）用于升级矿山浪费的环保技术，以解决更循环的经济，以应对全球采用电动汽车预期的巨大矿井浪费的紧迫技术 - 企业经济挑战。同意的教育，劳动力发展以及与研究计划保持一致和伴随的外展活动是在五个合作的学术机构中共同进行的课程和讲习班，以及当地社区大学，投票，中学和高中的各种外展活动。这项未来的制造奖得到了化学，生物工程，环境和运输系统（CBET）和民用，机械和制造创新（CMMI）的划分的支持。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛影响的审查标准来通过评估来通过评估来支持的。
