Magnesium phosphate cements (MPCs), are a class of new binders developed to reduce the ecological impact of construction. When magnesium oxide reacts with potassium dihydrogen phosphate (KH2PO4) (KDP) in presence of water, crystallization of magnesium potassium phosphate hydrate (MKP) occurs, according to the reaction: MgO + KH2PO4 + 5H2O --> MgKPO4·6H2O. Despite the importance of MPC for a wide range of applications, including rapid concrete repair, recycling of hazardous wastes, waste encapsulation, bone repair, natural fibre composites, no data are available on hydration reaction kinetics.
