(PDF) CONCRETE MIX, SLUMP AND CONCRETE COMPRESSION TEST ...

With a workable concrete mix, slump test and making concrete cubes was also done. Slump test When making the slump test, the base of the slump cone was put on a flat surface. The cone was then filled with wet concrete in three layers. Each layer was tempered 25 times with a standard 16mm (diameter steel rod, rounded at the end).

Tests on Concrete - Concrete Slump Test, Compression Test

2021-5-15  The slump test is done to make sure a concrete mix is workable. The measured slump must be within a set range, or tolerance, from the target slump. Workability of concrete is mainly affected by consistency i.e. wetter mixes will be more workable than drier mixes, but concrete of the same consistency may vary in workability.
