The invention discloses potassium magnesium phosphate cement and belongs to the field of cement. The potassium magnesium phosphate cement is prepared from 34-40% of KH2PO4, 43-49% of MgO, 7.2-8.8% of Al(H2PO4)3, 3.3-4.9% of glass fibers, 1-1.8% of ethylenediamine tetramethylenephosphonic acid potassium salt, 0.4-1.2% of a phosphomonoester coupling agent, 0.4-0.8% of sodium triphosphate and 0.9-1.3% of EDTMPS. The potassium magnesium phosphate cement has the advantages that the heat expansion coefficient is low, and formed cracks are reduced after curing.
