rtable fine filter segregation for crushed aggregates

Workability - Penn State Engineering

For a constant water/cementious material ratio, an increase in the aggregate/cementious material ratio will decrease workability, also, more cementious material is needed when finer aggregate gradings are used. A fine aggregate deficiency results in a mixture that is harsh, prone to segregation.
