Determine the workability of concrete:
The workability of concrete depends upon water content, shape, size and grading of aggregates, ratio of coarse and fine aggregates, and the use of admixture, if any. As it is difficult to quantify the workability by carrying out a single test, several tests are available to determine the workability of concrete mix like:
(a) Slump test,
(b) Compaction factor test,
(c) Flow test, and
(d) Vee-bee time test, etc.
