摘要： PROBLEM TO BE SOLVED: To provide a concrete composition, while suppressing the exhaust amount of carbon dioxide, which can secure satisfactory applicability in a state where the reduction in the fluidity and the reduction in an air amount with the lapse of time in the prepared concrete composition are suppressed, further can suppress the reduction in resistivity to the drying shrinkage and freeze-thawing of the obtained hardened body, and can make the required strength appear in the obtained hardened body as well. SOLUTION: The method for preparing AE (air entrained) concrete uses at least cement, water, fine aggregate, coarse aggregate and an admixture. As the cement, the following blast-furnace cement is used, also, the ratio of water/the blast-furnace cement is regulated to 30 to 60%, and further, per 100 pts.mass of the blast-furnace cement, as at least a part of the admixture, a specified cement dispersant, a specified drying shrinkage reducing agent, a specified AE adjuster and a specified defoaming agent are used. The blast-furnace cement is composed of blast-furnace slag fine powder having fineness of 3,000 to 13,000 cm 2 /g and portland cement, and also, the blast-furnace slag fine powder is comprised in a ratio of 60 to 80 mass% and the portland cement is comprised in a ratio of 20 to 40 mass% (total 100 mass%).
