The following tests are required to determine concrete’s workability. The tests are described below in a nutshell:
Concrete mixes having very low workability and unresponsive to slump test can participate in compacting factor test. This test is usually performed in laboratory and used in worksite too. Generally slump test is used to evaluate the consistency of fresh concrete. To get the complete slump test details step by step visit the following link.
Compacting factor test
Concrete mixes having very low workability and unresponsive to slump test can participate in compacting factor test. This test is usually performed in laboratory and used in worksite too.
This test counts on the basis of the principle of finding out the degree of compaction obtained by an ordinary quantity of work done by authorizing the concrete to fall through a standard height.
Compacting factor = (weight of partially compacted concrete) / (weight of fully compacted concrete)

Flow Test
This laboratory test provides a sign of the quality of the concrete regarding constancy, cohesiveness and the tendency to isolation. The expansion of the flow of the concrete is calculated and this is associated with workability. This test is best fit for flowing concrete made by the super plasticizing admixtures’ usage.
Kelly Ball Test
This is a simple field test containing of the determination of the indentation made by 15 cm diameter metal hemisphere weighing 13.6 kg when freely put on fresh concrete. It is moderately quicker and offers clear-cut measurement of workability than slump test. But it needs huge quantity of concrete to be executed.
