A slump test and a cylinder penetration test were conducted for 155 kinds of concrete with different grading of fine aggregate and different mix proportion, and a flow test was conducted simultaneously for wet-screened mortar. Additionally, the consideration based on the excess paste theory was conducted. The following findings were obtained as the results. (1) The segregation degree of concrete is evaluated quantitatively by an inflow mortar value, the result of the cylinder penetration test, and the inflow mortar value corresponding to the limit of segregation is 30 mm. (2) The fluidity of matrix mortar has a dominant influence on the segregation degree of concrete. Furthermore, the new procedure of mix design which can reasonably consider the segregation resistance of concrete was proposed based on these findings.
