Abstract: A mix-design method for self-compacting concrete proposed by Okamura et al. in 1993 is based on the assumptions that moderate-heat Portland cement or belite-rich Portland cement is the only source of powdered materials, and coarse aggregate volume and fine aggregate volume are limited. However, powdered materials and aggregates with varying properties will have to be employed if resources are to be effectively utilized in the future. Therefore, a mix-design method for applying various properties of concrete materials is desired. The authors investigated the interactions between coarse aggregates and particles in fresh mortar to establish such a mix-design method, and then developed a method for fixing proper fine aggregate ratio in mortar for achieving self-compactability corresponding to the properties of the materials by using a funnel test for mortar with model coarse aggregate in 1999. A method for fixing proper volumetric water-powder ratio and superplasticizer dosage for applying various properties of concrete materials by using mortar flow and funnel tests was also developed in 1997 and 1998. This paper proposed a conventional mix-design method for self-compacting concrete improved on Okamura's method by incorporating the methods for fixing fine aggregate ratio, volumetric water-powder ratio and superplasticizer dosage.
