Magnesium Phosphate Cement Formula

Magnesium Phosphate Cement an overview

02-07-2010· D.W. Fowler, in Failure, Distress and Repair of Concrete Structures, 2009. 7.2.10 Magnesium–phosphate cement (MPC) MPC is a blend of magnesium oxide (M g O) and ammonium dihydrogen phosphate (NH 4 H 2 PO 4) that reacts with water to rapidly produce heat and strength.MPC concrete comes prepackaged with cement, aggregates, and other fillers and admixtures.

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

This results in an initial gel formation followed by the crystallization of this gel into an insoluble phosphate, mainly magnesium ammonium phosphate hexahydrate, NH4MgPO4.6H2O. The magnesium oxide used in this system is a fairly unreactive MgO, either hard or dead-burnt, and is used in conjunction with a set retarder, typically either borax or boric acid, to afford a workable set time.
