4 Myths About Volumetric Concrete Mixers

Volumetric Mixers Use New & Unproven Technology.
The patent for concrete mobile mixers was granted more than a half century ago in 1965. By 1980, more then 2,500 units have been produced and the number surpassed 10,000 by 2000. Volumetric mixers can be found in use throughout the United States in every state, along with more than 60 countries around the world.
Volumetric Mixers Cannot Match The Accuracy & Consistency Of A Batch Plant.

False. Concrete mobile mixers are designed and
calibrated to meet ASTM C685; ACI 304.6R and AASHTO
M241 specifications. All materials have the same
tolerances while there are more restrictions placed on
ready mix since water-cement contact occurs at the
plant and not at the job site as is the case with volumetric
mixers.

Volumetric Mixers Cannot Produce A Good Or High-Quality Concrete.

Different mix designs of concrete need a design-specific amount of time to adequately mix. Volumetric mixers produce a wide range of designs, many of which are used in many everyday projects, such as:

  • Airport runways including repairs.
  • Bridge deck overlays.
  • Soil retention.
  • Structural elements.
  • Swimming pools.

These units are also capable of creating specialized types of concrete, such as lightweight concrete with foam.

Volumetric Mixers Are Undersized For Large Pours And/Or Projects

The edge that helps volumetric mixers stand out from traditional barrel mixers is the ability to be reloaded at a job site without wasted fuel and production time. Projects finished on, if not ahead of schedule, plus, the production rates of volumetric equipment can exceed 90 cubic yards per hour. The most common model of volumetric mixers available today produces one cubic yard each minute.
