Concrete posts are commonly used in many farm and agricultural applications. Portland cement and steel reinforcements are used to make these concrete posts. Production of Portland cement is responsible for a large amount of greenhouse gas (GHG) emissions and hence, use of Portland cement needs to be reduced significantly. Steel reinforcements are susceptible to corrosion. Corroded steel reinforcement swells, resulting in spalling of concrete and ultimately damaging the concrete posts. Hence, the objective of this research is to develop and test alternative concrete posts that are environmentally sustainable and not susceptible to corrosion-induced damage. Portland cement will be replaced with alternative cementitious materials such as slag and silica fume, which are industrial waste materials. These waste materials are currently dumped in the landfills, causing toxicity and other problems for the soil and people living nearby. Recycling of such waste materials will reduce GHG emissions and alleviate landfill problems. Steel reinforcements will be replaced by basalt fibre reinforcement. Basalt fibre reinforcement is corrosion resistant and slightly stronger than traditional steel reinforcement. Additionally, basalt fibre reinforcements are produced from volcanic rock called basalt and hence, basalt fibre reinforcement is an environmentally friendly material. Incorporation of industrial waste materials and basalt fibre reinforcement will make the new concrete posts environmentally sustainable and a cheaper alternative to currently used traditional concrete posts. Additionally, the state-of-the-art 3D concrete printer will also be introduced to reduce waste in concrete materials in the production of concrete posts and increase the productivity. This research will be executed by one doctoral student and two undergraduate students who will be trained in various aspects of green construction and use of 3D printing in the construction. These highly trained and skilled students will be able to bridge the skills gap in Canada. The industry partner, MEDA Engineering & Technical Services will gain a competitive edge in their business which will lead to new job creations.

混凝土柱常用于许多农场和农业应用中。波特兰水泥和钢筋用于制作这些混凝土柱。波特兰水泥的生产会排放大量温室气体 (GHG)，因此需要大幅减少波特兰水泥的使用。钢筋容易腐蚀。腐蚀的钢筋膨胀，导致混凝土剥落并最终损坏混凝土柱。因此，本研究的目的是开发和测试环境可持续且不易受到腐蚀损坏的替代混凝土柱。波特兰水泥将被矿渣和硅灰等工业废料等替代胶凝材料取代。这些废料目前被倾倒在垃圾填埋场，对土壤和附近居民造成毒性和其他问题。回收此类废料将减少温室气体排放并缓解垃圾填埋场问题。钢增强材料将被玄武岩纤维增强材料取代。玄武岩纤维增强材料耐腐蚀，强度略高于传统钢筋。此外，玄武岩纤维增强材料是由称为玄武岩的火山岩生产的，因此，玄武岩纤维增强材料是一种环保材料。工业废料和玄武岩纤维加固的结合将使新的混凝土柱具有环境可持续性，并且是目前使用的传统混凝土柱的更便宜的替代品。此外，还将引进最先进的3D混凝土打印机，以减少混凝土柱生产中混凝土材料的浪费并提高生产率。这项研究将由一名博士生和两名本科生执行，他们将接受绿色建筑和在建筑中使用 3D 打印等各个方面的培训。这些训练有素、技术精湛的学生将能够弥补加拿大的技能差距。行业合作伙伴 MEDA 工程与技术服务公司将在其业务中获得竞争优势，从而创造新的就业机会。
