SLUMP TEST $-$ SANS $5862-1$

$6\mathrm{.}1.$ Why is it important to do a slump test on fresh concrete prior casting?

This test is used to check the consistency or fluidity of concrete in a batch. The Slump

test measure the workability of the concrete or the ability of concrete to flow, workability

related to the type of construction, placing and finishing methods. This is a routine

procedure carried out in a fresh concrete mix to determine its consistency before it is

poured. The test is used to check that multiple batches of the same concrete are

consistent.
