Abstract

Magnesium oxychloride (MOC) cement is gaining renewed attention as a low-carbon construction material. However, conventional MgO production is constrained by the geographically limited availability of MgCO3 and its energy-intensive calcination at temperatures up to 1000 °C. Thermal recycling of wast...
