The use of volumetric proportioning and continuous mixing is well proven and has many advantages over traditional drum type mixers that rely on batching plants.
The volumetric mixer is essentially a mobile batching plant. It carries all the ingredients of concrete in a number of hoppers which feed into a continuous mixer.
This method allows the operator to mix any amount of fresh concrete on site, to any mix design, with no waste. The mix design can also be changed instantly, producing different types of concrete from the same load.
Another major advantage is that multiple deliveries can be made from one load, making small deliveries profitable. Road traffic is also reduced compared to traditional ready mix resulting in environmental benefits and can reduce congestion charges.
Many contractors prefer volumetric concrete because a fresh mix provides improved workability. As mixing takes place on site there is no hydration or segregation during transit. This is particularly beneficial in hot climates or for deliveries to remote locations.
It is also excellent for deliveries that require intermittent demand.
The volumetric mixer can easily produce a number of different types of concrete including pigmented, admixtures, fibre enhanced and foamed concrete. These high value concretes are produced exceptionally well and significantly more economically than with conventional mixers.
Volumetric mixers don't just deliver a commodity, they offer a complete concrete service.
