Magnesium Phosphate Cement - an overview |

2010-7-2 · 4.2 Magnesium phosphate cement. MPC is generated by an acid–base reaction between MgO and soluble phosphoric acid (usually ammonium or potassium phosphate) to form a magnesium phosphate salt with cementitious characteristics (Wang et al., 2017c). This kind of materials is known broadly as MPC (Walling and Provis, 2016).

Magnesium potassium phosphate cement paste: Degree

2014-11-1 · More strictly, the ADP-based MPC can be termed as magnesium ammonium phosphate cement (MAPC), as the main reaction product in the cement paste is magnesium ammonium phosphate (MAP) hexahydrate, with the formula MgNH 4 PO 4 ·6H 2 O, which is a naturally existing crystal more commonly known as struvite .
