Workability of concrete is defined as the ease and homogeneity with which a freshly mixed concrete or mortar can be mixed, placed, compacted and finished. Strictly, it is the amount of useful internal work necessary to produce 100% compaction.
Another similar term used to describe a freshly prepared concrete is ‘consistency’ which is the ease with which it will flow. It is the wetness of the concrete and the measure of fluidity or mobility. Wet concretes are more workable than dry concrete, but concretes of the same consistency may vary in workability.
A concrete which has high consistency and which is more mobile, need not be of right workability for a particular job. Type of work, thickness of section, reinforcements and mode of compaction are the aspects to be considered while specifying the workability for any particular job.Click here to continue read
