The mortar using magnesium phosphate cement (MFC) exhibits various fresh properties and physical properties after hardened depending on the cement composition, fine aggregate/cement ratio, and dosage of a set-adjusting agent. The author conducted several mortar tests to check the nature. Test results reveal the following characteristics that MPC mortar exhibits: 1) compressive strength development of 15N/mm^2 or more after one hour curing at a 20℃ environment, 2) excellent strength development at low temperature, 3) almost eaual properties in volume change and thermal coefficient of expansion to that of ordinary portland cement concrete. 4) low drying shrinkage, 5) excellent adhesive strength to substrate irrespective of the type of concrete and treatment methods, 6) superior chemical resistance, and 7) no corrosiveness to reinforcement because phosphate that is a component of MPC, is a corrosion inhibitor.
