In order to achieve a concrete end-product that possesses high quality, it must be consolidated properly. During the consolidation process, the concrete’s beauty, uniformity, durability and strength is take into account. To consolidate concrete, one of the most popular methods utilizes vibration. The technique subjects fresh concrete to vibratory impulses to liquefy the mortar and reduce internal frictions between its aggregate particles. After, the concrete is left settle under the effects of gravity and may be aided by other foreign forces – allowing vibration to stop and friction to return. In this article, you will learn what important factors to know when using external concrete vibrators.

How will your concrete vibrators be mounted?

Knowing how to mount your vibrators is the important first step in creating your concrete vibration plan. Thus, there are several factors you should consider like selecting between permanent or portable mounts, labour, cost, versatility, product life as well as vibration transfer.

Enhances repeatability and predictability in your concrete’s quality

When using external concrete vibrators, there are multiple variables that can affect concrete quality. One of the main variables could be the craftsmanship and skill of internal vibrator personnel. As compared to the United States, internal vibrator personnel in a European country must complete at least a decade of apprenticeship to attain his or her license.

However, operators from the United States need not fulfil the aforementioned requirements and can operate without formal training or a license. Simply put, the internal vibrator personnel’s equipment, technique, focus and skill have a major impact on the concrete’s finish quality. External concrete vibrators, on the other hand, provide users a known variable that can be adjusted and fine-tuned to meet specific requirements in repeatable and predictable ways.

Benefits of fresh concrete that has been properly vibrated

When concrete has been vibrated in a proper manner, it is actually the best way to prevent honeycombing, bug holes and cold joints. Hence, it is pertinent that operators rest concrete forms on rubber mats or wooden beams to prevent the form from vibrating against any ground surface and surrounding forms. When using external concrete vibrators, it also very important to reinforce and stiffen the forms to ensure even vibration transfer and leak prevention.

Always plan ahead when using external concrete vibrators

Sound planning, including keep spares at hand, is a good way to make all your concrete operations run smoothly and as planned. Some examples include:

  • Ensure sufficient air supply for your pneumatic vibrators
  • Have a neat and tidy work-site to ensure a quality finished product
  • Reinforce or tighten any formwork if needed
  • Realize a clear pattern of movement and placement of your vibrators
  • Pre-install brackets if necessary

These preparations also help to reduce time-consuming and costly processes when redoing or repairing concrete due to defects. Also, you will gain a solid and in-depth understanding of the vibration techniques that are needed to prevent discrepancies.

External concrete vibrator placement and layout is critical

Depending on how you positioned your vibrators, it has a range of influence from its current location. If you are unsure where you should place your vibrators, it is highly recommended that you consult with a concrete vibrator expert for more advice.
