报告内容简介：

The United Nations' 17 Sustainable Development Goals (SDGs) highlight the urgent need to transition from conventional to sustainable materials, with green materials playing a key role in achieving 13 of these goals. This lecture explores the sustainability of concrete, beginning with adjustments to mix proportions for targeted improvements and the development of a decision matrix for multicriteria analysis. The sustainability of concrete was further enhanced by replacing conventional aggregates with recycled or waste materials. A comprehensive framework was then developed to integrate technical, environmental, and economic performance, incorporating factors such as durability, life cycle assessment, and life cycle cost. Additionally, multicriteria analysis combined with big data was employed to prioritize sustainable material options. One example discussed is the use of calcined clay in the development of limestone-calcined clay cement (LC3), demonstrating how green materials can significantly contribute to reducing environmental impact while maintaining performance standards.

This study focuses on developing sustainable construction blocks through geopolymerization, an eco-friendlier alternative to traditional masonry fired-clay/cemented bricks. Fired-clay bricks, one of the oldest construction materials, have seen rising demand due to urbanization. However, their manufacturing process involves maintaining high temperatures (1000 – 1350 ºC) for several days, which significantly impacts energy consumption and the environment. While fluxing and fueling wastes have been used to reduce temperatures, they have had minimal effect, as temperatures still exceed 1000 ºC. Geopolymerization offers a greener solution, requiring much lower temperatures (up to 200 ºC). This study aimed to develop geopolymer blocks by uni-axial compression through detailed experimental investigations. Fly ash (FA), clay, red mud, lime, dune sand, sugarcane bagasse ash were used as precursors. The results showed that the combination of pressure and temperature optimized the strength of FA-based geopolymer bricks. A pilot-scale brick meeting desired strength requirements was successfully produced under ambient curing conditions with 20 MPa molding pressure, complying with relevant standards and codes.
