    Bleeding And Segregation

    In more severe cases, segregation of aggregates can also occur, with the heavier coarse particles moving towards the bottom of the concrete, leaving a cement sand paste layer on the top surface. Excessive working of a concrete prone to bleeding can prolong bleeding and encourage further aggregate settlement.

    Apr 01, 1971 Most authorities, however, feel that bleeding is a phenomenon which should be avoided or minimized in most construction situations. Concrete with a great deal of mobile water tends to segregate as it stands in the plastic state. The larger aggregates and larger cement particles gravitate toward the bottom of the mix with the finer aggregates ...

    Typical causes of bleeding are either applying too much binder, or using aggregate which is too flat. The solutions to this problem are either to reduce the asphalt application rate to the proper amount so that residual asphalt is 70 of the aggregate height or to use a more cubic aggregate.
