Zusammenfassung:PROBLEM TO BE SOLVED: To provide a cement admixture, a cement composition, and a cement mortar using them, in which viscosity is low, there is not aggregate separation, workability is favorable, curing is performed in a short time, and a longer age strength is achieved.SOLUTION: A cement admixture includes: a quick hardening material including calcium aluminate glass or calcium aluminosilicate glass, and gypsum; a setting retarder; spherical silica; colloidal silica; and calcium hydroxide. A cement composition includes: cement; the cement admixture including the quick hardening, the setting retarder, spherical silica, colloidal silica, and calcium hydroxide; and an aggregate. A production method of cement mortar comprises blending: a binding material including the cement and the quick hardening material; the setting retarder; the spherical silica; the colloidal silica; calcium hydroxide; the aggregate; and water.
