This Small Business Innovation Research Phase I project is focused on the reuse of waste glass to generate sustainable replacements for standard building envelope materials such as concrete and masonry. The materials being developed are comprised of over 95 percent waste glass and contain no environmentally harmful additives. When compared to conventional masonry and concrete products, they require up to 80 percent less energy to produce, and have a reduced carbon footprint. However, the process to manufacture these materials imparts a unique internal microporous structure that results in inadequate control of moisture penetration. This project will investigate the strength characteristics of the material and will explore the viability of applying environmentally responsible sealants to reduce or eliminate moisture absorption. The Phase I research will result in the development of methods for applying sustainable coatings, coupled with a subsequent analysis of sealant compatibility and hydraulic characterization of the composite material. A variety of sealants will be characterized based on final application requirements. The Phase I program will lead to the production of samples for evaluation by clients and partners in a variety of application settings. The broader impact/commercial potential of this project is significant. Successful completion of our Phase I activities will have a positive impact on both the glass recycling and building industries. The research in this proposal will establish a new approach for glass manufacturing and will provide a commercial outlet for waste glass, particularly the vast quantity that cannot currently be recycled, and therefore is simply hauled to the landfills. This material will allow manufacturers to adopt cost-effective green product lines and will also bring value to the construction industry by providing a truly green alternative to traditional facing materials. The environmental and societal impacts of this novel building material include improving environmental quality by decreasing energy consumption, and the associated greenhouse gas emissions, and by minimizing the burden on the solid waste storage infrastructure.

这个小型企业创新研究第一阶段项目的重点是废旧玻璃的再利用，以产生标准建筑围护材料(如混凝土和砖石)的可持续替代品。正在开发的材料由95%以上的废玻璃组成，不含对环境有害的添加剂。与传统的砖石和混凝土产品相比，它们需要的能源减少了高达80%，碳足迹也减少了。然而，制造这些材料的过程提供了一种独特的内部微孔结构，导致对水分渗透的控制不足。该项目将调查材料的强度特性，并探索应用对环境负责的密封剂来减少或消除吸湿性的可行性。第一阶段的研究将导致开发应用可持续涂料的方法，并随后分析密封剂的兼容性和复合材料的水力特性。将根据最终应用要求确定各种密封剂的特性。第一阶段计划将导致制作样品，供客户和合作伙伴在各种应用环境中进行评估。这个项目的更广泛的影响/商业潜力是巨大的。我们第一阶段活动的成功完成将对玻璃回收和建筑行业产生积极影响。这项提案中的研究将建立一种新的玻璃制造方法，并将为废玻璃提供一个商业渠道，特别是目前无法回收的大量废玻璃，因此只需将其运往垃圾填埋场即可。这种材料将允许制造商采用具有成本效益的绿色产品线，并通过提供传统表面材料的真正绿色替代方案，为建筑业带来价值。这种新型建筑材料的环境和社会影响包括通过减少能源消耗和相关的温室气体排放来改善环境质量，以及通过最大限度地减少固体废物存储基础设施的负担。
