The broader impact/commercial potential of this Phase I project to enable the efficient collection, organization, maintenance, and analysis of a significant volume of reliable scientific data regarding the strength of varieties of concrete mixes from across the country and the world. It is envisions that such technology may improve the quality and safety of critical civil infrastructure, accelerate construction schedules, help optimize the performance and efficiency of construction contractors and engineers, and reduce environmental costs associated with excess cement usage. With the approval of the 2021 Infrastructure Bill, the U.S. will make the single largest investment in repairing and reconstructing the nation’s bridges and major roadways since the construction of the Interstate Highway System in the 1950s. Current concrete strength test methods are cumbersome, costly, timeinefficient, prone to error and environmentally unfriendly. Development and commercialization of a reliable, cost-effective, user-friendly Internet of Things (IoT)-based electromechanical impedance sensing system that directly measures, in real-time, in-place concrete strength without reliance on the destructive testing of concrete samples has the potential to improve the civil infrastructure industry by providing reliable data analytics. This Small Business Innovation Research (SBIR) Phase I project is aimed at determining the strength of in-place concrete, in real time, using a piezoelectric sensor and electromechanical impedance (EMI) analysis. Destructive compressive strength testing (American Society for Testing Materials (ASTM C39) and maturity testing (ASTM C1074)) are the two primary methods used to determine strength development of concrete; however, both methods rely upon the creation and destruction of concrete samples which is inefficient and unreliable as well as harmful to the environment (both due to the concrete waste caused by sampling and the excess cement usage driven by the tendency of concrete samples to show low strength). The proposed research will test a variety of concrete mixes for strength over various time points. The proposed technology requires no concrete sampling or destruction, compared to both destructive compressive strength testing and maturity testing. Successful completion of this program may result in development of a prototype of a piezoelectric concrete strength sensor and customized datalogger capable of automatic data acquisition, processing, and transmission and a customized database to directly communicate in-place concrete strength data to contractors via a secured cloud server and highly intuitive graphical user interface.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.

该第一阶段项目具有更广泛的影响/商业潜力，能够有效收集、组织、维护和分析有关全国和世界各地各种混凝土混合物强度的可靠科学数据。可以提高关键民用基础设施的质量和安全性，加快施工进度，帮助优化建筑承包商和工程师的绩效和效率，并降低与过量使用水泥相关的环境成本。随着 2021 年基础设施法案的批准，美国将制定单身的自 20 世纪 50 年代州际公路系统建设以来，修复和重建美国桥梁和主要道路的投资规模最大。 目前的混凝土强度测试方法繁琐、成本高昂、时间效率低、容易出错且对环境不友好。经济高效、用户友好的基于物联网 (IoT) 的机电阻抗传感系统，可直接实时测量现场混凝土强度，无需依赖混凝土样品的破坏性测试，具有该小型企业创新研究 (SBIR) 第一阶段项目旨在利用压电传感器和机电阻抗 (EMI) 实时确定现浇混凝土的强度。破坏性抗压强度测试（美国材料试验协会 (ASTM C39) 和成熟度测试 (ASTM C1074)）是用于确定混凝土强度发展的两种主要方法；然而，这两种方法都依赖于混凝土的创建和测试。破坏混凝土样品是低效、不可靠的，而且对环境有害（由于取样造成混凝土浪费，以及混凝土样品强度较低导致的过量水泥使用）。与破坏性抗压强度测试和成熟度测试相比，所提出的技术不需要混凝土取样或破坏，成功完成该计划可能会导致压电混凝土强度传感器原型的开发。以及能够自动获取数据的定制数据记录器采集、处理和传输以及定制数据库，通过安全的云服务器和高度直观的图形用户界面直接向承包商传达现场混凝土强度数据。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
