Meaning of Ready Mixed Concrete

Ready Mixed Concrete is a type of concrete that is specifically produced in a factory or batching plant based on set specifications. Once prepared, the concrete is transported to the construction site in transit mixers mounted on trucks. Ready mixed concrete ensures higher durability and sustainability due to the precision in the mixture, which is crafted by expert suppliers. This method of production also allows for specialized concrete mixtures to be created efficiently for various projects.

Types of Ready Mixed Concrete

There are three main types of ready mixed concrete:

1. Transit Mixed Concrete (Dry Concrete)

In transit mixed concrete, all the components, including water, are loaded directly into the vehicle mixer. The agitator drum rotates at a high speed during loading and then continues to rotate at a normal agitation speed during transport to keep the concrete mixed and workable. This method is often referred to as "dry concrete" because mixing is done in transit.

2. Shrink Mixed Concrete

With shrink mixed concrete, the concrete is partially mixed in the plant mixer and the remaining mixing is completed in the truck's drum mixer during transit. The amount of mixing required in the transit mixer depends on how much mixing was done at the plant. Tests are typically conducted to determine the right balance for mixing in transit.

3. Central Mixed Concrete

Also known as central batching plant concrete, this type involves thoroughly mixing the concrete at a central plant before loading it into the truck mixer. The truck then serves only as an agitator, maintaining the concrete's consistency during transportation. In some cases, non-agitating units or dump trucks can be used if the workability requirements are lower or the distance to the site is short. Central-mixed concrete offers the advantage of better handling and more accurate mixing, which can reduce cement consumption by 10-12%. The use of additives and other cementitious materials further helps minimize cement use, providing an eco-friendly solution.

Benefits of Ready Mixed Concrete

• Higher quality and precision in mixing.
• Durability and sustainability due to the expert preparation process.
• Efficient production of special concrete mixtures tailored to specific project needs.
• Reduced cement consumption through accurate mixing, resulting in cost savings and environmental benefits.
