This paper describes new producing method of flowing concrete by using of powdered superplasticizer(PS) packed in paper material rapidly decomposable in fresh concrete (PS A). Solubility of PS in fresh concrete .composition of paper material, influence of PSA to the concrete properties were studied and field investigations were carried out. The results are as follows: The solubility of PS in fresh concrete was much improved by adding with silica fume to PS. The paper material made from 20wt% of carboxymethyl cellulose and 80wt% of pulp was suitable for packing PS. There was little difference between the properties of the flowing concrete added with PSA and those of the one added with liquid superplasticizer. In the field investigation, the properties of the flowing concrete added with PSA in truck agitators were mostly within the standard value of JASS-5. Consequently, the flowing concrete added with PSA is able to be used practically.
