| Research Abstract |
The investigation to establish the mix design of concrete considering reasonably aggregate grading was conducted. In consequence, (1) it was clarified that the variation of grading of fine aggregate within the range specified in JIS has a great effect on the fluidity and the segregation resistance of concrete. Additionally, (2) the method to control these effects by adjusting mix proportion of concrete was prepared. Furthermore, (3) the equation to estimate solid content from grading of aggregate was constructed and the aggregate filling simulator was developed.
