It is important to compact the concrete fully because: air voids reduce the strength of the concrete. for every 1 of entrapped air, the strength falls by somewhere between 5 and 7. this means that concrete containing a mere 5 air voids due to incomplete compaction can lose as much as one third of its strength.
