    • 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.
    • 流动的混凝土及其生产过程。 将水泥,水,骨料,超增塑剂和偏析控制剂捏合到水灰比为约35%或更低的基础混凝土中,所述分散控制剂的含量为约0.02至约0.1wt 。 %,基于水并包括甲基纤维素化合物,并且所述超增塑剂的含量为约0.25至约0.6重量%。 基于水泥的%。 然后,约0.25至约0.6wt。 添加到基础混凝土中的基于水泥的流动剂固体的%,流动剂包括磺酸/甲醛高缩合物和聚乙烯醇。 此外,将具有流动剂的基础混凝土揉成流动的混凝土。
