flows without segregation of coarse aggregate from the finer material. Mixtures of such consistency are suitable for most work. The ease or difficulty of placing and consolidating concrete is called workability. Concrete should be workable; it should not be so stiff or so wet that segregation occurs; nor should it bleed excessively.
