The broader impact/commercial potential of this I-Corps project is the development of a device to predict the performance of key construction materials in a matter of few minutes. Construction materials and chemicals are required to undergo a quality control process via standardized specifications and performance tests. Globally, there is a strong push for decarbonizing energy-intensive industries, such as cement production, which accounts for 6-8% of global carbon emissions. In the short term, the cement industry is looking to reduce its carbon footprint by partially replacing cement with sustainable supplementary cementitious materials (SCMs). The replacement of cement with low-carbon SCMs is estimated to be able to result in CO2 savings of up to 30 percent. One of the barriers faced by the industry is the highly variable quality of these low-carbon SCMs and the lack of real-time methods for quality control. Quality control managers and cement kiln supervisors at cement plants across the world are looking for reliable, online quality control tools. The proposed technology may enable better quality control for newer SCMs, which may facilitate their application in the cement industry. In addition, this may open pathways for rapid, online quality control of low carbon building materials.This I-Corps project is based on the development of a rapid analytics device for real-time quality control of sustainable supplementary cementitious materials (SCMs). Newer materials proposed to replace cement in order to speed up the decarbonization of the concrete sector are reliant on traditional, time- and labor-intensive quality control tests that may take up to 7 days. This proposed technology is based on previous research on the chemistry of SCMs, and combines fundamental principles of low-cost material characterization and analysis. The analysis obtained from various natural and commercial SCMs using the proposed technology are consistent with the performance measured using current standard methods. In addition, the proposed technology reduced the performance prediction time from days to minutes, which may enable real-time characterization in the production line. Further, this device may have an economic advantage over current practices as it utilizes low-cost detection equipment to allow automatic operation.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.

该I-Corps项目的更广泛的影响/商业潜力是开发一种设备，以预测几分钟内关键建筑材料的性能。需要建筑材料和化学品通过标准化规格和性能测试进行质量控制过程。在全球范围内，脱碳能源密集型行业（例如水泥生产）占全球碳排放量的6-8％。在短期内，水泥行业希望通过用可持续的补充水泥材料（SCM）部分代替水泥来减少其碳足迹。据估计，用低碳SCM替换水泥可以使二氧化碳节省高达30％。该行业面临的障碍之一是这些低碳SCM的高度可变质量以及缺乏质量控制的实时方法。世界各地水泥厂的质量控制经理和水泥窑主管正在寻找可靠的在线质量控制工具。 拟议的技术可以为更新的SCM提供更好的质量控制，这可能有助于其在水泥行业中的应用。此外，这可能为低碳建筑材料的快速，在线质量控制开放。该I-Corps项目基于开发快速分析设备，用于实时质量控制可持续补充水泥材料（SCMS）。 为了加快混凝土部门的脱碳而提议取代水泥的新材料依赖于传统，时间和劳动力密集型质量控制测试，最多可能需要7天。该提出的技术基于先前对SCMS化学的研究，并结合了低成本材料表征和分析的基本原理。 使用所提出的技术从各种天然和商业SCM获得的分析与使用当前标准方法测量的性能一致。 此外，提议的技术将绩效预测时间从几天减少到几分钟，这可能会在生产线中实时表征。此外，该设备可能比当前的实践具有经济优势，因为它利用低成本检测设备来允许自动操作。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的审查标准，被认为值得通过评估来获得支持。
