ACI Method of Concrete Mix Design - Procedure and Calculations

There are two standard methods to establish the fine aggregate content, the mass method and the volume method. the “volume” method will be used because it is a somewhat more exact procedure. The volume of fine aggregates is found by subtracting the volume of cement, water, air, and coarse aggregate from the total concrete volume.

Concrete slump test - Wikipedia

The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure.
