Different Types of Ready Mix Concrete


Ready mix concrete refers to the custom-made concrete manufactured in a central plant and batched for delivery on the construction site. This kind of concrete guarantees higher sustainability and durability. There are many companies ready mix concrete. However, ready mix concrete by DTM is regarded as superior than that of others.

Concrete is the most common material in a construction site. There are different ways to ensure your safety in dealing with concrete such as using the right equipment for concrete cutting, applying concrete scanning process, and repairs.

Ready mix concrete is a cost-effective and environmentally friendly choice for your specific concrete needs. They are made available in three different types, and each of them has a specific mixture of ingredients.

1. Transit mixed concrete:

Otherwise called dry-batched concrete, the transit mix concrete combines all the important ingredients along with water into the mixer truck. The truck’s mixer drum is rotated fast at appropriate speed during the initial loading of the requisite materials. Once done, the drum continues to rotate at a normal speed. Transit mix concrete has three different variations, and these are explained in brief.

  • Concrete mixed at the construction site – During the transportation of the mixture towards its destination, the drum is made to rotate at a slow speed of about 2 rpm. When the truck reaches the construction site, the drum is made to rotate at a maximum speed of 12 to 15 rpm. This way, the mixture becomes smooth before it gets transferred from the truck.
  • Concrete mixed during transit – The term itself is self-explanatory. It means the mixture is allowed to rotate continuously during transit at medium speed of approximately 8 rpm for about 70 revolutions. Once the said revolutions are completed, the rotation is reduced to 2 rpm. The same is maintained until the mixtures reach the construction site.
  • Concrete mixed in the yard – The truck’s drum is made to rotate at 12 to 15 rpm for about 50 revolutions. That allows the experts to check the batch for a quick inspection. The concrete mixture is slowly agitated while driving to the construction site on a mixer truck.

2. Shrink mixed concrete:

In this type of mixture, the concrete is partially mixed in the original factory mixer. And, the remaining mixing is completed in the truck with mounted rotating drum during the transit time. Here, the amount of mixing concrete during a transit depends greatly on the extent of mixing done before it was mounted on the truck.

It means the mixer that was partially done in the original concrete mixing plant. Tests should be done to find out the amount of mixing to be done on the mounted drum during transit. These tests would be carried out by the experts who are trained for these tasks.

3. Central mixed concrete:

It is another type of ready mix concrete. Otherwise called a central batching plant, the concrete gets thoroughly mixed before it is loading on the truck mixer drum. The concrete is mixed in a stationary plant mixer and poured into the mixer truck.

The plant is often mentioned as pre-mix, and sometimes as wet-batch. During the transportation of the concrete, the mixer in the drum behaves like an agitator only. In rare situations, when the lead is less or the workability requirement is very low, dump trucks or other non-agitating vehicles are made use of for transporting the concrete mixture.
