The Ultimate Guide to Volumetric Concrete

There are a few different types of concrete, and in this guide, we are going to focus on volumetric concrete, giving you all the information you need to understand it.

Volumetric concrete is mixed on site at your premises, right in front of you. The main benefit of this is that it allows for last minute changes as the mix is made - this is particularly useful if there are sudden changes in weather, as concrete can be adversely affected by the elements. It’s also useful if you discover you need more or less concrete than originally thought.

When do you need volumetric concrete?

Volumetric concrete is needed if you have a project where the amount of concrete required isn’t certain. The very basis of volumetric concrete is that it can be altered on the go, which means even the most last minute of last minute hitches doesn’t have to derail your entire project. The mix can be reduced or added to at a moment’s notice, so if the requirements suddenly change, you can adapt quickly.

Volumetric concrete is also preferable for projects where speed is not the priority. It is still an efficient process, but mixing on-site inevitably takes up a bit of time, especially when compared to ready mixed concrete which arrives pre-mixed, as the name suggests.

Volumetric Mixer
Vehicle Specification

  • Capable of delivering concrete at 1m3 per minute, or slower if you prefer.
  • Can deliver concrete or screed.
  • Our Mixers are approximately 11 meters long and 3 meters wide.
  • We produce a wide range of concrete batched on site from C8 to C40 and you only pay for what you use.
  • The mix can be changed according to your needs there and then.
  • Each mixer carries 2 wheelbarrows which are free for you to use.
  • All mixers have an extension chute that can reach 5 meters from the back of the lorry giving you that extra reach if needed.
  • Cost effective, quick, clean and efficient with no wastage.

The Process

The process works as follows:

  1. The first step is the design of the mix - this is done using a control panel on our trucks, where the various requirements are entered
  2. The aggregate then flows onto a conveyor belt which takes it through the truck
  3. Cement is added through the cement feeder - also known as a ‘sock’
  4. Water is then added to the mixture using a small hose, then flowing into the mixing bowl
  5. The computer measures the exact amount of aggregates, cement and water is added to the mixing bowl, the batch is then mixed using the mix auger
  6. Once finished, the mix will flow down the chute and out of the truck. If it needs to be moved to a different location, ground or boom pumps can be connected to the truck to transport the concrete

The computers on board these trucks allow for the most meticulous of mix designs, catering for projects of all types and scales. Once the perfect mix has been created, it can be pumped quickly and with minimal mess to the desired location. What’s more, if there are changes in circumstances or requirements, the mix can be altered at a moment’s notice - no need to worry about delays or forced downtime.
