Development of waste-based magnesium cement for CO2 capture and storage
| Resumo: | This doctoral thesis presents the development of a novel Carbonated Reactive Magnesia Cement (CRMC) for the production of precast building materials. The research objectives centred on the co-utilisation of industrial, mineral, and non-mineral wastes, along with CO2 mineralisation, to enhance the sustainability of construction practices. This study encompassed a comprehensive investigation of various influencing factors of CRMC synthesis, including accelerated carbonation curing conditions, mixture designs, and production methodology. Through a critical review of the literature and joint systematic experimentation aimed at refining manufacturing methods and improving mixture designs, the research achieved a substantial understanding of the feasibility of incorporating a wide range of waste materials into CRMC. Furthermore, the study sought to explore the use of waste as a partial substitute for industrial-grade magnesia, with the aim of enhancing the ecological profile of CRMC-based materials. The research outcomes have significantly contributed to the advancement and dissemination of knowledge in the field of CRMC-based materials, the utilisation of waste in construction, and the development of precast materials with capacity of CO2 mineralisation and co-utilisation of various waste sources. In conclusion, it is apt to state that this thesis aligns with a global trend aiming for a more environmentally-friendly and resource-efficient construction industry, offering a possible alternative to traditional Portland cementbased materials. |
