| Outline of Final Research Achievements |
In order to skip ultimately a trial mixing to adjust workability of concrete, the investigation to establish mix design method of concrete considering reasonably the gradings of cement, fine aggregate and coarse aggregate was conducted. In consequence, it was clarified that the fluidity of cement paste, mortar or concrete can be predicted to some extent by the distance between particles calculated from the grading of overall particles of powder and granular material composing that, that is the mixture of cement, fine aggregate and coarse aggregate.
