Magnesium Phosphate Cement (MPC) Scientific.Net

The results show that magnesium phosphate cement has good resistance to sulfate erosion, especially the anti-corrosion ability of magnesium sulfate. However the alkali resistance of the magnesium phosphate cement is poor. Therefore, the magnesium phosphate cements are not appropriate to be used in alkaline environment as cementitious material.

Magnesium Phosphate Cement: Characteristics and

Magnesium phosphate cement (MPC) hardens rapidly and gains high strength in a short time, ranging about several hours to the level of normal strength of ordinary Portland cement concrete. The magnesium phosphate cement binder is produced from the reaction between magnesium oxide and phosphate in water at room temperature.

2021-7-6  Abstract. Although Ordinary Portland Cement (OPC) is the main cement considered in relation to industrial and radioactive waste management (as being the most widely used in the world), several waste types are incompatible with OPC. In particular, magnesium potassium phosphate cements (MKPC) are more suited to some waste types.
