Flowing concrete with high flowability prepared with a river sand;river gravel and a crushed sand; crushed stone was investigated for mixture proportions, flowability, strength, shrinkage, carbonation and freezing and thawing resistance. The main findings can be summarized as follows. (1)The slump of the flowing concrete sufficiently filled up with a slight compaction ranges from 24 to 26 cm, which corresponds to a flow from 50 to 60 cm and a differential height less than 8 cm in the box test. (2)Flowing concrete with a water-cement ratio from 30% to 60% can be made by using two new admixture and by a simple correction of the standard table of the mixture proportion. (3)Flowing concrete can be produced with a specified concrete strength ranging from 180 to 600 kgf/cm^2.
