The objective of this research project is to develop a novel design methodology for a class of fiber-reinforced composite materials, combining the greenness of geopolymers with the enhanced durability of Engineered Cementitious Composites (ECC). Sustainable alternatives to energy intensive, high carbon footprint, Ordinary Portland Cement (OPC)-based building materials are needed in order to meet the needs of both new construction and to maintain existing infrastructure in harmony with the natural environment. True sustainability demands both material greenness and enhanced durability, which lowers the need for costly and environmentally unfriendly repair work. These new Engineered Geopolymer Composites (EGCs) will provide a highly sustainable alternative to OPC-based materials for infrastructure systems, an alternative that is badly needed and not currently provided by any other materials. On a societal level, this project will touch the life of every person by producing truly sustainable construction materials that substantially lower the energy consumption and carbon production of the building and construction industries. Replacing even one percent of OPC-based materials with EGCs would be equivalent to taking millions of cars off of the road. Further, the novel design methodology will be adaptable to numerous fields beyond civil engineering, leading to more efficient materials development elsewhere. Locally, high school and college students will benefit as the results of the research are incorporated into classes (both at the university and through remote learning) and demonstration projects. The research will also be incorporated into an established local pre-college engineering program, intended to increase the number of minority students in engineering.

该研究项目的目的是为一类纤维增强的复合材料开发一种新型的设计方法，将地球聚合物的绿色与工程胶合材料（ECC）的耐用性增强相结合。 为了满足新建建筑的需求并与自然环境和谐相处，需要可持续替代能源密集型，高碳足迹，普通波特兰水泥（OPC）的建筑材料。 真正的可持续性需要物质绿色和增强的耐用性，从而降低了对昂贵和环境不友好的维修工作的需求。 这些新的工程地球聚合物复合材料（EGC）将为基础架构系统提供基于OPC的材料的高度可持续性替代品，这是一种急需的替代方案，目前不受任何其他材料提供。在社会层面上，该项目将通过生产真正可持续的建筑材料来触及每个人的生活，从而大大降低建筑物和建筑行业的能源消耗和碳的生产。 用EGC替换一个基于OPC的材料的百分之一等同于将数百万辆汽车撤离道路。 此外，新颖的设计方法将适用于土木工程以外的许多领域，从而导致其他地方的有效材料开发。 在本地，高中和大学生将受益，因为研究结果被纳入了课程（无论是在大学还是通过远程学习）和示范项目。 这项研究还将纳入一项既定的当地大学前工程计划，旨在增加工程学中的少数族裔学生的数量。
