When slabs are cast, the surface is levelled out with a screed board which also is used to compact the concrete mix as soon as it has been placed to remove any trapped air. The less workable the mix is, the more porous it is and the more compaction is necessary. For every per cent of entrapped air the concrete loses up to 5% of its strength.
