Why Concrete Vibrators Are Important for a Great Final Product

Why Concrete Vibrators Are Important for a Great Final Product

Are you a concrete or masonry contractor seeking ways to optimize your projects' results? Air bubbles may pose an issue when creating and pouring a concrete mix. These bubbles can form when air doesn't combine with water and cannot escape the mixture, resulting in voids or cavities in the slab that weaken its structural integrity. Concrete vibrators can alleviate this issue and produce a better, more durable finished product. 

What Is a Concrete Vibrator?

A vibrator is a piece of construction equipment specifically designed to eliminate trapped air bubbles from concrete mixtures. The machine consists of three core components:

  • Motor: A vibrator has either a gas- or electric-powered motor that serves as the machine's operating force. 
  • Whip: The whip extends the machine's vibration to the level required to complete the job. The motor spins the whip's internal core and produces high-frequency vibration. Rubber casings help to protect the whip from extreme heat during operation to prevent damage to the motor.
  • Head: The head is an elongated part connected to the whip — this component penetrates the concrete surface and produces the vibrating action. 

What Do Concrete Vibrators Do?

A concrete vibrator produces a vigorous shaking action that removes bubbles from freshly poured concrete. It's essential to perform the process at the appropriate speed to achieve the best results. In most cases, withdrawing the machine from the surface at a rate of approximately an inch per second will deliver the most effective outcome. You should continue the process until no more air bubbles emerge.

The Different Concrete Vibrator Types

Concrete vibrators are available to perform various vibration functions:

  • Formwork: These are typically used in precast construction projects and require mounting the machines to the exterior of the concrete forms. The proper spacing of the vibrators depends on the size of the pouring project.
  • Surface: A surface vibrator is the best option when working with a concrete slab depth of 6 inches or less. It also produces a smooth surface for projects where appearance is important.
  • Internal: Use this most common vibrator type for standard concrete pouring projects.
