Though slump test is originally designed as a measure of workability, it turns out to be an indicator of excessive water content in concrete only.
Slump test is not considered as a measure of workability because:
(i) There is no connection between the test results of slump test and workability;
(ii) The test results exhibit large random variations which is greater than that due to observed differences in workability;
(iii) Concrete of different workability may have the same slump.

If you have a query, you can ask a question here.
Workability is the ease with which concrete can be worked with, And slump test shows retention of concrete. So doesn’t that mean slump test can show the retention of concrte implying for how long concrete can be worked with?? Please explain.
Are there any calculation formulaes or example for the slump test?
“Sometimes the same slump value of concrete could have the different workability” so what cause(s) of this phenomenon?
Slump value affected by concrete different grades?
what is the weight of slump cone apparetus
can you pls tell me the consistency limits ranges for very low,low,medium consistency?
which is the best method of measuring workability and why
