A concrete composition is provided comprising a nonionic water-soluble cellulose ether, water, cement, a fine aggregate, and a coarse aggregate. The nonionic water-soluble cellulose ether has a 2 wt% aqueous solution viscosity of 3-1,000 mPa·s at 20°C. The concrete composition has a static slump/remix slump ratio of at least 0.50. |
