In an effort to develop binders with a reduced environmental impact, magnesium silicate hydrate (MSH) cement has recently attracted considerable attention. This binder belongs to the family of magnesium-based cements; however, unlike magnesium sulphate and magnesium oxychloride cements, it is classified as a hydraulic cement. It forms through the reaction of reactive magnesium oxide with silica sources in the presence of water, producing magnesium silicate hydrate (MSH) gel. Caustic-calcined magnesite, typically p...
