Compaction of Concrete - Boral

Compaction of concrete is, therefore, a two-stage process Figure 1. First the aggregate particles are set in motion and slump to fill the form giving a level top surface. In the second stage, entrapped air is expelled. It is important to recognise the two stages in the compaction process because, with vibration,
