The invention discloses multi-component potassium magnesium phosphate cement, belonging to the field of cement. The multi-component potassium magnesium phosphate cement comprises the following components in percentage by weight: 34%-40% of KH2PO4, 43%-49% of MgO, 7.2%-8.8% of Al(H2PO4)3, 3.3%-4.9% of glass fiber, 1%-1.8% of sodium carboxymethylcellulose, 0.4%-1.2% of a phosphomonoester coupling agent, 0.4%-0.8% of sodium tripolyphosphate and 0.9%-1.3% of ethylene diamine tetra(methylene phosphonic acid) sodium. The multi-component potassium magnesium phosphate cement has the characteristics that a pore structure is relatively perfect, and the crack formation is reduced after the solidification.
