　　Magnesia-phosphate cement(MPC)is a kind of new cementing material composed of magnesia(MgO)powders,phosphate and setting retarder and so on.In order to explore the influence of calcined magnesia,fly ash and boric acid retarder on the performance of magnesium-phosphate cements(MPC),original magnesia was calcined under different condition,which were mixed with fly ash and some retardes to prepare different MPC samples.
