- Aim: To find out the compaction factor for the given fresh mix of concrete.
- Theory: Workability of concrete is the ability/ease with which concrete can be mixed, transported and placed. This is a major factor which contributes to the other properties of concrete also. If concrete is workable enough then it can be compacted with less compacting effort.
So there is a relation between the amount of work required to compact a given fresh concrete and the work-ability of the concrete. This relation is well suited for the concrete of the low water cement ratio. Slump cone test is also used to find out the work-ability of the concrete but only recommended for the concrete of higher work-ability. For less workable concrete(having less water cement ratio), compaction is standardized by various standards.
- Apparatus: Compaction factor apparatus/machine, weighing balance, cow/mixing tray.
- Result: The compaction factor of the given fresh concrete mix is .....
