You are currently viewing A Summary Of The Different Types And Variations Of Ready Mix Concrete And Their Advantages

Concrete is one of those rare resources that have been in use for many centuries. With only a few changes over the years, it is still almost the same as the earlier concrete. But with modern conveniences and growth over time, the way concrete is used for construction has also seen changes. One of the main differences is the use of cement and how concrete is mixed. Concrete is rarely, if ever, mixed on construction sites anymore. There are manufacturing plants, cement factories or batch plants where they are mixed and then the delivery to construction sites is taken care of using various modes of transport.

Ready Mix Concrete is made with the same basic ingredients as any other, namely, cement, sand, aggregates and water. Admixtures are added to the mix according to the need at the construction sites. Other than admixtures, the composition volume of each base ingredient can be varied to produce various mixes serving a wide variety of needs. This can be done to increase or reduce the strength, alter the drying time, delay drying and more. Let us take a look at these different mixes and how they can be advantageous to construction projects.

The Different Types Ready Mix Concrete

Transit Mix Concrete

This refers to the concrete that is mixed during the transport of concrete from manufacturing plants to construction sites. In this method, the constituents required to create concrete mix are loaded onto trucks and mixed during transit. This can be seen in three different types, let us take a look at them below:

1. Mixed On-Site

This is not the same as mixing concrete on construction sites. In this method, the concrete is mixed at a slow pace during transit. Once the concrete truck with all the ingredients arrives at the side, then the mixing speed is quickened to get a mix that is thoroughly mixed and smooth.

2. Mixed During Transit

In this case, the components of concrete mix are loaded on the trucks just like the previously mentioned method. But the difference is that the mixing is thoroughly completed during transit and then the mixer barrel rotates at a much slower speed until it reaches the site and it can be delivered. This is to keep the concrete agitated until it can be delivered.

3. Concrete Mixer in Yard

The concrete is mixed slowly during transit to keep the mix agitated. Once the truck has reached the site of delivery, the speed is picked up and the mixing is completed and ready for delivery.

Central Mixed Concrete

This is used when a specific quality of concrete is required at the site. Central mixed concrete, often known as wet mixed concrete is where the concrete is first prepared and then tested. These tests are done to ensure quality and strength. When the concrete quality is approved then it is transferred to the site ready to be used. This mix is made in batch plants with an eye for preciseness.

Shrink Mixed Concrete

Shrink mixed concrete is appropriate when large amounts of concrete are required at the sites. The concrete mix, as required, is prepared at the batch plants to the specifications preferred at the site. This mix is then loaded onto the concrete transport trucks and is delivered.

The Various Advantages Of Ready Mix Concrete An Efficient Concrete Mix And Delivery Method

Mixing concrete on-site consumes a lot of labour and time and not to mention it will also require post concrete mix clean up. But with Ready Mix Concrete, the required amount, strength or special mix can be communicated to the manufacturing plants with the schedule of when the concrete will be required. They will then mix it as per the preferred mix design and deliver it on time. This will save time, produce a high-quality concrete mix and keep the site clean.

Consistency And Quality

Ready Mix Concrete delivers the highest quality of concrete with perfect consistency every time. This is because the concrete is mixed in batch plants where the measurements and mixing are highly controlled and automated. This results in perfectly mixed and high-quality concrete each time.

Environmentally Friendly

Mixing the concrete in batch plants reduces the emission of dust and other materials during the mixing process. The batch plants are often well away from populated areas, reducing the effect on people. Moreover, it also ensures that the exact required amount of concrete is mixed and in precise amounts so that overproduction is stopped.

Reducing Concrete Wastage

Often concrete is wasted at construction sites due to overproduction or wrong mixes. This can be stopped completely with Ready Mix Concrete. As it is mixed in batch plants, the desired quantity can be produced largely reducing the need for overproduction. Moreover, batch plants can mix the perfect mix, reducing wastage due to imperfect mixes.

Summary

Adding to all of these benefits, concrete delivery is also highly convenient and mess-free with Ready Mix Concrete. The trucks are specially designed to keep the concrete fresh and ready for use on sites.
