We first investigated the relationship between the final bleeding capacities of 8 series of concrete, occurring in the cylinder of JIS method and in the filling side of a U-shaped filling box with two types of obstacles. Estimating early the final bleeding capacity of fresh concrete with steel reinforced bars, we measured the bleeding capacity of fresh concrete after vibrated for 10 seconds and kept still for 20 minutes in a special cylindrical container, and got two relational formulas between the test results of bleeding capacities in the cylindrical container and the U-shaped filling box. |
