WEBFeb 5, 2020 · Vibrating Concrete Makes It Stronger. When concrete is poured into a form, it naturally forms air bubbles. These air bubbles create voids in the final, reducing the actual amount of concrete by as much as 20 percent. That's a significant amount and can weaken the final product. The process of consolidation uses vibrations to remove these air ...
