Informations de la recherche : Canada’s industrial strategy emphasizes reducing reliance on carbon-intensive cement, while promoting innovative use of by-products to advance green construction technologies. Developing geopolymer concrete pipes from bauxite residue directly supports these goals, offering a pathway to resilient, low-carbon infrastructure systems that contribute to climate change mitigation and sustainable urban development. The project addresses two critical sustainability challenges: reducing greenhouse gas emissions associated with construction materials, specifically cement production, which accounts for nearly 8% of global CO₂ emissions, and valorizing industrial waste from the aluminium industry, which generates millions of tonnes of bauxite residue annually, much of which is landfilled. The project focuses on the development of geopolymer concrete using bauxite residue, targeting sustainable solutions for urban infrastructure. The primary objective is to produce durable precast concrete pipes with enhanced mechanical strength and chemical resistance, capable of withstanding aggressive service conditions while reducing the environmental impact associated with traditional cement-based products.
