The current trajectory of the global concrete industry is unsustainable, contributing significant amounts of greenhouse gas emissions and landfill waste. The proposed Discovery research program will address these critical issues by exploiting the unique advantages of fibre-reinforced polymer (FRP) composites as a potential catalyst to adopt a paradigm of reuse in the construction industry. This concept has been described as an industrial ecosystem in which one generation of structures becomes a resource to be repurposed for the next generation of structures. The long-term aim of the proposed research is to promote a circular economy within the construction industry to divert waste from landfills and reduce energy consumption, emissions, and the depletion of finite natural resources associated with concrete production. The research program will focus on four short-term objectives: 1) Develop FRP retrofitting techniques for deconstructed concrete structures to create opportunities for reuse within an industrial ecosystem; 2) Investigate the performance of reconfigurable FRP-concrete modular components designed to facilitate disassembly and reassembly; 3) Develop new demountable connection types for concrete structures using FRP materials; and, 4) Address the logistical and technical barriers preventing widespread reuse of concrete structures. This research program aims to create new knowledge related to a largely neglected, yet critical, issue of sustainable design. The reuse of concrete structural members is relatively unexplored, and provides an opportunity for significant disruption of the construction industry if technical and logistical challenges can be overcome. In the proposed research program, the inherent advantages of FRP materials will, for the first time, be investigated for the primary purpose of enabling the reuse of concrete components for multiple generations of structures within an industrial ecosystem. The proposed work includes several innovations related to novel uses of FRP in construction, as well as the durability and condition assessment of concrete structures. Additionally, the research program will ultimately lead to new design guidelines, inventory and rating systems for reclaimed structures, and condition assessment methods. This work will result in several benefits to Canada, including: 1) environmental benefits due to reduced emissions, energy use, landfill waste, and consumption of natural resources; 2) economic benefits associated with improved resource efficiency and lower life-cycle costs; 3) new market opportunities for disruptive Canadian businesses willing to embrace a new circular economy; and 4) the training of HQP which represent the next generation of engineers with unique skills, design experience, and expertise, as well as an understanding of sustainable development issues, durability, and asset management.

全球混凝土行业目前的发展轨迹是不可持续的，造成了大量温室气体排放和垃圾填埋。拟议的Discovery研究计划将通过利用纤维增强聚合物(FRP)复合材料作为潜在催化剂的独特优势来解决这些关键问题，以在建筑业采用重复使用的范例。这一概念被描述为一个工业生态系统，在这个生态系统中，一代结构成为一种资源，将被重新用于下一代结构。拟议研究的长期目标是在建筑业内促进循环经济，以转移来自垃圾填埋场的废物，并减少能源消耗、排放和与混凝土生产相关的有限自然资源的消耗。该研究计划将集中于四个短期目标：1)开发用于解构的混凝土结构的FRP加固技术，以创造在工业生态系统中重复使用的机会；2)调查旨在促进拆卸和重新组装的可重新配置的FRP-混凝土模块组件的性能；3)开发使用FRP材料的混凝土结构的新的可拆卸连接类型；以及，4)解决阻碍混凝土结构广泛重复使用的物流和技术障碍。这项研究计划旨在创造与可持续设计这一基本被忽视但却至关重要的问题相关的新知识。混凝土结构构件的再利用相对来说还没有被探索，如果能够克服技术和后勤方面的挑战，这将为建筑业的重大颠覆提供机会。在拟议的研究计划中，将首次调查FRP材料的固有优势，主要目的是使混凝土组件能够在工业生态系统中的多代结构中重复使用。拟议的工作包括与FRP在建筑中的新用途以及混凝土结构的耐久性和状况评估有关的几项创新。此外，该研究计划最终将导致新的设计指南、再生结构的库存和评级系统，以及状况评估方法。这项工作将为加拿大带来几个好处，包括：1)减少排放、能源消耗、垃圾填埋场和自然资源消耗带来的环境好处；2)与提高资源效率和降低生命周期成本相关的经济效益；3)为愿意接受新循环经济的颠覆性加拿大企业提供新的市场机会；以及4)培训HQP，他们代表着具有独特技能、设计经验和专业知识的下一代工程师，以及对可持续发展问题、耐久性和资产管理的理解。
