  • Batching, Mixing, Placing and Compaction of Concrete

    Mar 18, 2017 · 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. Air voids increase concrete's permeability. That in turn reduces its durability.
