项目摘要
This Broadening Participation Research Initiation Grants in Engineering (BRIGE) grant provides support to combine physical and chemical numerical tools to predict the performance of concrete made with glass filler. Waste glass that cannot easily be recycled into new glass has the potential to be used in concrete in place of part of the Portland cement, if the glass is finely ground. Both experimental and modeling approaches will be used to (1) measure the chemical reaction properties and rates for individual glass types of different fineness in concrete, (2) measure the water absorption and strength development of mortar containing ground glass, and (3) integrate the thermodynamics into an existing numerical tool that simulates the structural arrangement of the cement chemical reaction products. The model will then be used to simulate the mortar strength and water absorption when glasses of different type and fineness are used. Finally, a sensitivity analysis will be performed to determine the optimum grinding needed for mixtures of different glass types and fineness. The results of this research will potentially allow for increased commercial use of waste glass in concrete, benefiting both the environment and infrastructure. This project will reveal fundamental information about glass reaction in concrete that is currently lacking, but vital for modeling performance. The results of this study will provide insight into the mechanisms of other materials used to replace portions of the Portland cement in concrete, such as volcanic ash, ground granulated blast furnace slag, and coal combustion fly ash. The modeling component developed will also be applicable to the reaction of any particle system at variable temperature. The education plan, to be integrated with the research program, will result in a day-long program on recycling engineering for middle school-age girls and boys with representation from underrepresented groups. Evaluations from the participants will provide valuable insights into the role of gender in designing outreach programs.
这项扩大参与的工程研究启动补助金(Brige)提供了支持,以结合物理和化学数值工具来预测由玻璃填充物制成的混凝土的性能。如果玻璃磨得很细,不容易回收的废玻璃有可能用来代替部分波特兰水泥用于混凝土中。实验和模拟方法将被用来(1)测量混凝土中不同细度的单个玻璃类型的化学反应特性和速率,(2)测量含磨细玻璃的砂浆的吸水率和强度发展,(3)将热力学集成到现有的数值工具中,模拟水泥化学反应产物的结构排列。然后,使用该模型来模拟使用不同类型和细度的玻璃时的砂浆强度和吸水率。最后,将进行灵敏度分析,以确定不同玻璃类型和细度的混合物所需的最佳研磨。这项研究的结果可能会增加废玻璃在混凝土中的商业使用,使环境和基础设施都受益。这个项目将揭示关于混凝土中玻璃反应的基本信息,这些信息目前是缺乏的,但对模拟性能至关重要。这项研究的结果将为深入了解用于取代混凝土中部分硅酸盐水泥的其他材料的机理,如火山灰、磨细的高炉矿渣和燃煤飞灰。所开发的模拟组件也将适用于任何粒子系统在变温下的反应。这项教育计划将与研究计划相结合,将为来自代表性不足群体的中学年龄段的女孩和男孩提供为期一天的回收工程项目。参与者的评价将为性别在设计外联方案中的作用提供宝贵的见解。
