| 主权项 | 1. A concrete composition comprising a nonionic water-soluble cellulose ether, water, cement, a fine aggregate, and a coarse aggregate, wherein the nonionic water-soluble cellulose ether has a 2 wt % aqueous solution viscosity of 3 to 1,000 mPa·s at 20° C. and the concrete composition has a slump ratio (AB) of at least 0.60, wherein A is a static slump value of the concrete composition, B is a remix slump value of the concrete composition, and both the static slump value and the remix slump value are measured according to JIS A 1101. | ||
