摘要： A flowing concrete and a process of producing the same. A cement, water, aggregates, a superplasticizer and a segregation-controlling agent are kneaded into a base concrete having a water-cement ratio of about 35 % or less, the segregation-controlling agent contained in an amount of about 0.02 to about 0.1 wt. %, based on the water and including a methylcellulose compound, and the superplasticizer contained in an amount of about 0.25 to about 0.6 wt. % based on the cement. Then, about 0.25 to about 0.6 wt. %, in terms of the solid, of a flowing agent based on the cement is added to the base concrete, the flowing agent including a sulfonic acid formaldehyde high condensate and a polyvinyl alcohol. Further, the base concrete with the flowing agent is kneaded into the flowing concrete.
