Geopolymeric cement is a new kind of cementitious material activated by some chemical activator.The factors that affect the preparing of the geopolymeric cement were invistigated by laboratory experiments, including calcining temperature of kaolin, the compersition and dosage of alkali activator, and the dosage of water. The results show that the new cementitious material with high strength can be prepared as the kaolinite is calcined at 700℃,and holds about 2h ,and then the amorphous metakaolin is activated by sodium silicate solution （activated by NaOH 20wt%）with a cement/alkali ratio of 5：4, and water/ cement ratio of 0.3 ,respectively, and cured under autogenous conditions.
