FREQUENCY OF THE SLUMP TEST
It is important to do this test preferably in the first batch as soon as the concreting work starts. This is necessary so that correct water addition is
finalised to give the required workability. Thereafter this test is performed whenever the mix does not seem to be right and adjustment of water is
desirable.
Slump test is also necessary for every batch of concrete sampled for cube test so that in case of cube failure some conclusions can be drawn whether
the mix had more workability or in other words it had higher W/C than that of the recommended mix.
The slump test must be taken as soon as possible at about the same time after mixing.
