Which property does adequate compaction improve in concrete?

Adequate compaction significantly enhances the strength and durability of concrete. When concrete is properly compacted, air bubbles and voids within the mixture are minimized, creating a denser and more homogeneous material. This densification increases the load-bearing capacity of the concrete, contributing to its overall strength. Additionally, reduced porosity from good compaction leads to lower permeability, which helps protect the concrete from environmental factors such as moisture and chemicals. This improves the durability of the structure, making it more resistant to cracking and degradation over time. Stronger and more durable concrete is crucial for the longevity and safety of reinforced concrete structures.
