Compacting of the concrete

After placing the concrete, if its compacting is not done properly, the concrete may become hollow. With compacting, the air bubbles in the concrete get released, making the concrete dense and also increases its strength and durability. While compacting, keep the following points in mind:

Compacting of the concrete


For the smaller concrete works, use manual compacting such as rodding with the help of a steel rod or tamping with a wooden cross beam.


The mechanical compacting is done with the help of vibrators. This can make the compaction more effective.


Generally, needle vibrators are used for the structures like footings, beams and columns.


Take care that the shaft pipe of the vibrator should not bend too much as it can break the pipe.


Be sure to clean the needle and shaft pipe after work.
