Is It Possible to Make Magnesia-Based Cement Environmentally Friendly?
ACS Sustain Chem Eng
November 2024
Article Synopsis
- - This paper evaluates the environmental impact of magnesia-based cements using a life cycle assessment approach, focusing on four types of MgO and ten magnesia-based cements.
- - Results show that using Salt Lake magnesium residue in MgO production can cut CO emissions by over 60% compared to traditional methods, and incorporating alternative materials like fly ash can further reduce emissions by 16-45% in certain cements.
- - Among the cements studied, carbonation-reactive magnesium cement (CRMC) emerged as the most eco-friendly option, achieving a very low overall environmental impact indicator of 0.00078.
