Reactive MgO and Self-healing Microcapsules for Enhanced Well Cement Performance
… and CaO-based expansive additives, MgO has many advantages including a thermally stable hydration product, relatively low water requirements for hydration, and designable expansion properties. These make MgO a promising candidate for delivering the desired expansion under the complex …

The Role of Reactive MgO as an Expansive Additive in the Shrinkage Reduction of Concrete
Hard-burnt magnesium oxide (MgO) has been successfully used in large volume concrete, mainly dam construction in China, for thermal shrinkage reduction since the 1970’s. At ~4% addition to the cement by weight, it is much simpler than conventional shrinkage measures and in particular, reduces the …

Optimization of Struvite Recovery Utilizing Magnesium Oxide
Magnesium oxide (MgO) is a cost-effective and environmentally sustainable alternative to magnesium chloride (MgCl2) and sodium hydroxide (NaOH) used for sidestream struvite recovery from anaerobically digested supernatant (centrate) through the Pearl® process. MgO is produced from magnesite (MgCO3) …

Investigation into the Production of Carbonates and Oxides from Synthetic Brine through Carbon Sequestration
… Cement (PC) production. Therefore, innovative reactive magnesia cement, with significant sustainable and technical advantages, has been proposed by blending reactive MgO and hydraulic binders in various proportions. MgO is currently produced from the calcination of magnesite (MgCO3), emitting …

Synthesis and Characterisation of Layered Double Hydroxides (LDHs) Using Red Mud and their Environmental Applications
… as RM-LDHs and synthesised from Ireland RM and reactive MgO. The optimal experimental parameters were determined, which were CO32- solution environment, L/S ratio = 20, MII/MIII ratio = 3.0 and aging at 70°C for 72 h. RM-LDHs were recognised to be carbonates intercalated Mg2+/(Al3+, Fe3+)-LDH, …
