ABSTRACT:
Compaction is the governing factor for the strength, durability and serviceability of the concrete. During the placing of the concrete in the form air is likely to trap within the concrete body, hence the density of the concrete is decreasing; ultimately it affects the strength, durability and serviceability of the concrete body. Vibration is the best remedy for getting rid off the trapped air from the concrete. At earlier stages when advanced vibrators were not found generally hand compaction method were adopted, but nowadays is a trend to use mechanical compaction method for compaction of the concrete. According to the condition we can use immersion vibration, surface vibration, or from vibration. We must use such vibration method with certain precaution to avoid any damages.
KEYWORDS: Compaction, Vibration, Strength, Durability, Serviceability
INTRODUCTION
“Compaction is the process which expels entrapped air from freshly placed concrete and packs the aggregate particles together so as to increase the density of concrete.” The aggregate particles, although coated with mortar, tend to arch against one another and are prevented from slumping or consolidating by internal friction. Compaction of concrete is, therefore, a two-stage process.
In first stage with the vibration, initial consolidation of the concrete can often be
