Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an AE concrete composition using blast furnace cement having a small slump loss and little generation of bleeding water, excellent in freeze-thaw resistance, and further capable of obtaining an AE concrete composition having high fluidity by suppressing the viscosity to a low level when preparing a high-strength AE concrete composition.SOLUTION: In an AE concrete composition containing blast furnace cement, water fine aggregate, coarse aggregate and an admixture, and further containing an air amount adjusting agent, the ratio of water/blast furnace cement is 25-60%, a specific water-soluble vinyl copolymer of a two-component system or a three-component system is used as the admixture, and the 0.1-3 pts.mass admixture is used with respect to the 100 pts.mass blast furnace cement.
