A Review of Magnesium Oxide in Concrete Premier Magnesia

Magnesium oxide-based shrinkage-compensating concrete (MgO concrete) is concrete with an additive of lightly burnt MgO powder. When MgO hydration takes place, the final product is magnesium hydroxide, Mg(OH) 2. Because Mg(OH) 2 has a larger volume than its constituents, MgO concrete is expansive. Concrete made with more typical expansive

Sorel cement Wikipedia

Sorel cement (also known as magnesia cement or magnesium oxychloride) is a non-hydraulic cement first produced by the French chemist Stanislas Sorel in 1867.. In fact, in 1855, before working with magnesium compounds, Stanislas Sorel first developed a two-component cement by mixing zinc oxide powder with a solution of zinc chloride. In a few minutes he obtained a dense material harder than
