Methods of Concrete Compaction and Types of Vibrators

Leaner mix of concrete can be used to achieve the same strength. Hence it results in saving cement up to 10 to 15 % and better strength. It permits compaction of narrow or thin sections where hand compaction may be difficult. The resultant concrete is more impermeable, dense, and free from honeycombing.
