Zusammenfassung:	PURPOSE:To provide the cement admixture and cement composition to be used in the field requiring especially early strength and long-term strength. CONSTITUTION:The cement composition consists of a cement admixture consisting essentially of a calcium aluminosilicate glass contg. the oxide of a trivalent metal other than aluminum and gypsum and cement. When this admixture is used, the early strength and long-term strength are increased, and the cement is hardly crazed. Further, the admixture is used in the same way as before, and the admixture is widely applicable for the secondary product such as prefabricated product, road, building, tunnel, etc., requiring a desired strength in a short time, or as the road repairing, grouting and stopwater materials.
