The proposed research is a significant initiative to develop new technologies and strategies for pre-fabricated elements and sustainable structural design through the complete reuse and recycling of Construction and Demolition Waste (CDW), which is responsible of more than one-quarter of all waste generated in Canada. The overall objective of this program of research is to present globally applicable solutions to counteract the negative effects of CDW on the environment, the economy and society by developing pre-fabricated structural and non-structural elements that incorporate green construction materials, and by promoting and popularizing reuse and/or recycling in the construction industry. ***The specific objectives are to: (1) propose novel reuse and/or recycling methodologies that are substantially less energy intensive, more economical and more easily applicable for taking full advantage of CDW materials; (2) maximize the amount of reused and/or recycled CDW without compromising the prolonged sustainability and enhanced greenness of the final product; (3) modify reused and/or recycled ultimate products with green fibers for more versatile and widespread use; (4) merge ultimate reused and/or recycled green products into easily demountable structural and non-structural building systems to introduce sustainable deconstructable system designs; and (5) develop a holistic design and integrated inspection protocol for Green Lego-type Houses to identify their green construction performance. ***In-depth theoretical and experimental investigations will focus on recycling 100% of the inert portion of CDW to manufacture green concrete-based geopolymeric binder reinforced with vegetable and recycled green fibers, and to develop novel, environmentally sustainable masonry units and green foam concrete to be used in real-scale deconstructable building systems and sustainable design. ***Successful outcomes of this research will impact the construction industry by reducing CO2 emissions and limiting climate change. The long-term effects will benefit construction and demolition stakeholders, as outdated approaches are abandoned in favour of more environmentally friendly practices, contributing to the deceleration of global warming. Participating students will gain knowledge and experience that will qualify them to be a viable resource for both academia and the Canadian construction industry.

拟议的研究是一项重要的举措，旨在通过完全再利用和回收建筑和拆除废物（CDW）来开发预制构件和可持续结构设计的新技术和战略，CDW占加拿大产生的所有废物的四分之一以上。该研究计划的总体目标是提出全球适用的解决方案，通过开发包含绿色建筑材料的预制结构和非结构元件，并通过促进和推广建筑行业的再利用和/或回收，来抵消CDW对环境，经济和社会的负面影响。* 具体目标是：（1）提出新的再利用和/或再循环方法，这些方法的能源密集度大大降低，更经济，更容易应用，以充分利用CDW材料;（2）最大限度地提高再利用和/或再循环CDW的数量，而不影响最终产品的长期可持续性和增强的绿色性;（3）用绿色纤维改性再利用和/或再循环的最终产品，以获得更通用和更广泛的用途;（4）将最终再利用和/或再循环的绿色产品合并到易于拆卸的结构和非结构建筑系统中，以引入可持续的可拆卸系统设计;及（5）为绿色乐高积木式房屋制订整体设计及综合检验方案，以识别其绿色建筑表现。* 深入的理论和实验研究将侧重于回收100%的CDW惰性部分，以制造用植物和回收的绿色纤维增强的基于绿色混凝土的地质聚合物粘合剂，并开发新型的、环境可持续的砌体单元和绿色泡沫混凝土，用于真实规模的可解构建筑系统和可持续设计。* 这项研究的成功成果将通过减少二氧化碳排放和限制气候变化来影响建筑业。长期影响将有利于建筑和拆除的利益攸关方，因为过时的方法被放弃，而采用更环保的做法，有助于减缓全球变暖。参与的学生将获得知识和经验，使他们有资格成为学术界和加拿大建筑业的可行资源。
