What are advantage and disadvantage of compacting concrete using a steel rod?

One advantage of compacting concrete with a steel rod is that it effectively removes air bubbles, leading to a denser and stronger final product. This method allows for better control over the placement and helps ensure uniformity in the mix. However, a disadvantage is that it can be labor-intensive and time-consuming, and improper technique may cause segregation of the aggregates, potentially compromising the integrity of the concrete. Additionally, it may not be suitable for larger pours where mechanized methods would be more efficient.
