The preparation of the magnesium phosphate cement is introduced. The effects of the factors, such as the amount of borax, water-cement ratio, magnesium phosphorus ratio, age, mixing amount and length of CFRP chopped strands on the setting time, workability and the strength of MPC paste are studied. The results show that, MPC has the sig-nificant character of early-strong high-strength, with the increasing usage amount of CFRP strips, the bending and com-pressive strength of the specimen is increased significantly. When M:P is 1.8, W:B is 0.11, M:K:B is 153:85:5, the strength of specimen is equivalent the 52.5R Portland cement. When M:P is 1.8, W:B is 0.13, Vc is 15 ‰, the strength of speci-men is equivalent the 62.5R Portland cement.
