COMPACTION OF CONCRETE

Compaction is the process that expels entrapped air from freshly placed concrete and packs the aggregate particles together so as to increase the density of the concrete The compacting and finishing of concrete are generally two separate operations but sometimes particularly with flat horizontal surfaces they become parts of the one operation Get price Get Price
