Magnesium oxychloride cement definition is - a cement that is used only for interior work (as floors in hospitals and public buildings), is made by adding in proper proportions a strong solution of magnesium chloride to magnesia, and when used with small stones, wood flour, or cork sets to a hard mass in a short time and takes a high polish. The chemical formula is MgO.” ... had this to say "One area for research into partial cement replacements is the recently emerged family of reactive magnesia (MgO) cements.
