Vibration of the boom system is inevitably caused by periodic disturbances, which are induced by pumping concrete. In this paper, an active control strategy of constant-position commandless input shaping technique is developed to suppress vibration.

05.02.2020Vibrating 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

05.02.2020Vibrating the concrete consolidates it, which means it pushes the concrete into every part of the concrete form. It also blends parts of the concrete together to create a single mass with as few holes and lift lines as possible. Here's everything you need to know about how vibrations are used with concrete.

When concrete is poured it can consist of up to 20% air bubbles. The air also prevents concrete adhering to rebar. To ensure maximum strength as well as integrity, these bubbles should be removed before the concrete sets. Our range of powerful Vibrating Pokers help to bring the excess air and water to the surface, giving your concrete more density.
