IMPORTANCE & THEORY:
This test is performed to check the consistency of freshly made concrete. Consistency is a term very closely related to workability. It is a term which describes the state of fresh concrete. It refers to the ease with which the concrete flows. It is used to indicate the degree of wetness. Workability of concrete is mainly affected by consistency i.e. wetter mixes will be more workable than drier mixes, but concrete of the same consistency may vary in workability.
It can also be defined as the relative plasticity of freshly mixed concrete as indicative of its workability. So concrete may have the following types of consistency:
1) PLASTIC CONSISTENCY
2) SEMI-FLUID CONSISTENCY
3) FLUID CONSISTENCY
