Consolidation of plastic concrete is termed as compaction. In the process of compaction‚ efforts are only directed to reduce the voids in the compacted concrete. Compaction of concrete can be done either manually or mechanically. When it is done manually it is called hand compaction or tamping‚ and in second case it is termed as machine compaction. Hand compaction: Hand compaction is done with the help of steel tamping rods‚ or timber screeds. Marrow and deep members are compacted with tamping
