magnesium oxide cement additive

A Review of Magnesium Oxide in Concrete - Premier

2015-2-16  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

Cement Anti-shrinkage Additive GRECIAN MAGNESITE

Magnesium oxide can act as such an additive due to its volumetric expansion upon hydration. The reactivity of the MgO must be carefully adjusted to avoid premature or late hydration, depending on the application. Calcined magnesium oxides provide early expansion while deadburned MgOs provide delayed expansion effects. See also Drilling Cements.
