In its simplest form, three basic ingredients are required to make concrete – cement (the binder), aggregates (ranging in size from fine to coarse) and water. Cement reacts with water to form hardened silie compounds that bind all of the individual aggregate components together into one homogenous material – concrete.

Compaction of concrete is, therefore, a twostage 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, initial consolidation of the concrete can often be achieved relatively .
