Low CO2 reactive magnesia cements and their applications via nano-modification

With low calcination temperature of around 750°C–900°C, strength gain via CO2 sequestration, and the ability to be fully recycled, reactive magnesia cement (RMC) is a potential low CO2 binder for construction applications. This chapter presents the recent development of RMC and its applications via nano-modification. Details of research work up to date on the production of RMC, the hydration and carbonation mechanisms of RMC-based formulations and their improvement via nano-modification, the mechanical properties of nano-tailored RMC-based composites, as well as the applications of RMC in developing novel cementitious binders are presented.
