How is concrete consolidated?

The manual consolidation methods are generally used only on smaller nonstructural concrete placement. Plastic or more flowable mixtures may be consolidated by rodding. Spading— in which a flat tool is repeatedly inserted and withdrawn adjacent to the form—is sometimes used at formed surfaces.

Techniques for Consolidating Concrete

If the thickness of the concrete to be consolidated is greater than the area of influence of the vibrator, or if a higher-quality finished surface is required on both sides, the contractor should locate alternate vibrators on opposite form walls. For instance, the first vibrator is placed on the front wall and the next is 5' (1.5 m) away but on the back wall. See illustration below
