2019.3.6 4.2.1 Mechanical Compaction. The most widely used method for compaction is vibration. Vibration consists of subjecting freshly placed concrete to rapid vibratory impulses, which liquefy the mortar, and reduces the internal friction between aggregate particles, thereby resulting in the proper settlement of concrete.

2021.3.7 Major Causes for Honeycombing. 1. Poor Workability of Concrete. Concrete with low workability is not cohesive and consistent, and thus, will result in either segregated concrete or concrete with honeycombs i.e. voids, resulting in leakage and low strength. Therefore, it requires a lot of effort in handling, placing and compaction, in particular.

The answer is “Yes”. If concrete honeycombing expands to large area, exposes steel bars, and penetrates 5 cm or more into the concrete, it can be very problematic. Repairs need to be made as soon as feasible to the damaged area. It changes structural members’ appearance as well as their strength and durability, shortening their useful lives.
