Which Is Better: Volumetric vs. Drum Concrete

In the construction industry, concrete is an essential material used in various applications for its durability and versatility. There are different types of concrete, and in this guide, we’ll be focusing on volumetric and drum concrete. We’ll discuss each type’s pros and cons and for which applications they’re best suited.

What Is Volumetric Concrete?

Volumetric concrete, as implied by its name, is concrete that’s mixed according to volume instead of weight. Also known as on-site mixed concrete, this type of concrete is made through volumetric concrete mixers, which are specialist trucks containing sand, cement, and other materials used for creating concrete.

What Is Drum Concrete?

Also known as barrel mix, drum concrete is a type of concrete already manufactured in a factory or batching plant instead of being made on-site. Once the mixture is prepared, the batch is then delivered to the construction site.

Pros and Cons of Volumetric Concrete

Pros

  •       Allows for customisation: Since volumetric concrete is made on-site, adjustments can be made to ensure you have the right type of concrete for your project.
  •       Cost savings: Compared to ready mix, volumetric concrete involves only mixing what you need.
  •       Flexibility: Contractors can change the mix depending on factors like the weather and other unexpected issues.

Cons

  •       Inconsistent quality: Experienced operators are needed to ensure the quality of the mix stays consistent.
  •       Has the potential to produce excessive dust

 

Pros and Cons of Drum Concrete

Pros

  •       Consistent quality: Since the mix is created in a factory or batching plant, the quality of the concrete typically stays consistent.
  •       Time savings: Barrel mix concrete can be directly delivered to the construction site for more efficiency.
  •       Reduced labour: There’s no need to create the mix on-site.

Cons

  •       Limited adjustability: Since the mix is already prepared, there’s little to no room for contractors to make adjustments.
  •       Potential for waste: Estimating how much concrete you’ll require may result in some amounts not being used, resulting in waste.

 

Applications and Best Uses for Each Method

Volumetric Concrete

  •       Ideal for projects requiring various mixes
  •       Suitable for remote locations
  •       Great for small to medium-sized projects that require on-site customisation

Drum Concrete

  •       Best for large-scale construction projects
  •       Ideal for projects with tight schedules
  •       Suitable for projects with easily accessible locations

FAQs

What is the difference between a drum mixer and a volumetric mixer?

A drum/barrel mixer prepares ready-mix concrete in batching plants or factories. A volumetric mixer, on the other hand, is used for mixing concrete on-site.

What is volumetric concrete used for?

Volumetric concrete is used for various construction projects, such as building foundations, driveways, and more.

What are the disadvantages of a volumetric concrete mixer?

Some of its disadvantages include requiring an experienced contractor to operate and the potential to produce excessive dust.
