This Small Business Innovation Research (SBIR) Phase II project is focused on the reuse of waste glass to generate high-value replacements for traditional masonry products. Masonry manufacturers cannot meet the construction industry's needs with their status quo product and are therefore losing market share. The industry seeks products with higher quality, consistency and performance that address environmental concerns, while remaining cost competitive. The material which has been developed meets or exceeds all required performance standards, and its high recycle content and low embodied energy significantly reduce production costs. The research objectives for this Phase II project include scale-up of this process via extrusion and expansion of the usable waste glass supply. The transition to extrusion will require increasing the plasticity of our material and research will result in extrudates that are compatible with masonry production equipment. The effort will also explore the impacts of contamination on the microstructure and mechanical performance of glass materials sintered at low temperature; this work will be the first of its kind. The ultimate project goal is successful development of the first high-recycle content glass composite paste that is ready for industrial manufacturing via cold extrusion.The broader impact/commercial potential of this project is significant. Successful completion of the Phase II activities will have a positive impact on both the glass recycling and construction industries. One key result will be the development of a novel, high-efficiency glass manufacturing process. This work will contribute to the scientific understanding of plasticity theory and mechanical behavior with respect to glass composites and porous materials. The evaluation of organic and inorganic contaminants, as they relate to advanced glass processing technologies, will be the first research of its kind. This research will provide a commercial outlet for waste glass, particularly the vast quantity that cannot currently be recycled, and therefore is simply hauled off to landfills. This material will allow manufacturers to adopt high-value, cost-competitive 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 associated greenhouse gas emissions, and also by minimizing the burden on solid waste storage infrastructure.

这个小型企业创新研究（SBIR）二期项目的重点是废弃玻璃的再利用，以产生传统砌体产品的高价值替代品。砌体制造商的现有产品不能满足建筑行业的需求，因此失去了市场份额。该行业寻求具有更高质量，一致性和性能的产品，以解决环境问题，同时保持成本竞争力。所开发的材料达到或超过了所有要求的性能标准，其高回收含量和低蕴含能量显著降低了生产成本。该二期项目的研究目标包括通过挤压和扩大可用废玻璃供应来扩大该工艺的规模。过渡到挤压将需要提高材料的可塑性，研究将导致与砌体生产设备兼容的挤出物。研究污染对低温烧结玻璃材料微观结构和力学性能的影响；这项工作将是同类工作中的首例。该项目的最终目标是成功开发出第一个高回收含量的玻璃复合浆料，并准备通过冷挤压进行工业生产。这个项目的广泛影响/商业潜力是巨大的。第二期工程的顺利完成将对玻璃回收业和建造业产生积极影响。一个关键的结果将是一种新的，高效的玻璃制造工艺的发展。这项工作将有助于科学地理解关于玻璃复合材料和多孔材料的塑性理论和力学行为。有机和无机污染物的评估，因为它们涉及到先进的玻璃加工技术，将是同类研究中的第一个。这项研究将为废玻璃提供一个商业出口，特别是目前无法回收的大量废玻璃，因此被简单地拖到垃圾填埋场。这种材料将使制造商能够采用高价值，具有成本竞争力的产品线，并通过提供传统饰面材料的真正绿色替代品，为建筑行业带来价值。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，同时也通过最大限度地减少固体废物储存基础设施的负担。
