The invention discloses composite potassium magnesium phosphate cement, and belongs to the field of cement. The composite potassium magnesium phosphate cement comprises the following components: 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 dodecyl benzene sulfonate, 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 composite potassium magnesium phosphate cement disclosed by the invention has the characteristic of few crack, i.e., cracks can be reduced after the cement is cured.
