Ready mix plants, also referred to as a batching plant, for concrete allows builders to manufacture customized cement and transport that mixture to the construction site as and when required. The product is normally transported from the ready mix plants using truck mounted transit mixers. This enables customized concrete to be produced which is required on the construction sites. The world’s first ready mix concrete plant was set up in 1930s, but the actual boom in the industry began in 1960s, and has never looked back since.
Ready Mix Plants
The main purpose of concrete ready mix plants is to provide concrete to construction sites on a timely basis. When a batch of ready mix concrete is required, the nearest plants are normally favored in order to minimize transport time and cost. At the plant, raw materials are stored in hoppers and silos and mixed using advanced computerized systems. The ready mixed concrete plant is required to equip itself with up-to-date equipments, such as transit mixer, concrete pump, and concrete batching plant, which needs visualized production management software and also PLC controller. Experienced batchers continuously monitor the processes to ensure that the quality of cement meets the expectations of the client.
HOW DO READY MIX PLANTS WORK WITH MATERIALS?
• Hydration: After raw materials, water, and cement are combined, the mixture remains in a fluid state for about 5 hours, allowing transportation, placements and finishing at the intended building site. During hydration, cement crystals radiate and mesh with crystals of water and other raw materials, resulting in stiffening and hardening of cement. Once the cement is thoroughly mixed, it should be placed at the required places before it sets.
• Proportioning: This involves proportioning of a concrete mix design to make it economical and enable it to achieve the properties required for its intended use. The experts at the ready mixed concrete plant can select the material proportions for the performance you require, or you may specify your requirements yourself through job specifications.

Types
There are four different types of ready mix concrete.
• Truck Mixed Concrete: In this method, all the raw ingredients are mixed during the transit. Most of the water is batched at the plant and the mixer drum is turned at fast speeds during loading of the materials. The mixing can be done either at the job site, in the plant itself before dispatch, or during the transit period itself.
• Shrink Mixed Concrete: This method involves initial mixing in the plant mixer after which the concrete is loaded into the truck mixer to be mixed completely during the transit. The amount and time of mixing done in the truck mixer is determined using mixer uniformity tests.
• Central Mixed Concrete: The entire mixing process is completed in the plant mixer and the cement is loaded onto the truck mixer for transport. In this method, the truck mixer is used mainly as a transporter of the ready mix concrete.
Ready Mix Plants
Using ready mix concrete at your construction site could be an excellent decision which would result in higher efficiency and time savings along with reduced costs. Also, every load of concrete you use will be fresh as it has been mixed either on the way to the construction site or at the construction site itself. Moreover, large construction assignments such as road paving can depend on a consistent quality of cement in every truckload. Another aspect where costs are reduced is that labor at the construction site earlier used for cement production can be assigned other jobs, and there is also reduced requirement for storage space at the site.

This brought back memories, I used to work at a construction company and I ordered the concrete on multiple occasions. In the winter you have to have that quick dry stuff or Ash in it right? My boss would have me order that because the weather never being predictable he didn’t want to just put it down and hope that it dried before anything happened, this he thought would guarantee it.
I have no construction expertise, but I did see a reality show on the Discovery Channel which documented the challenges of several industries. In one of the episodes, a New York City construction company was featured during the construction of a new building. One of the biggest challenges when building a concrete structure is apparently the transportation of wet cement mixture to the construction site – getting the concrete there before it sets. I wonder if these ready mix facilities overcome this problem.
Concrete can be a very tough thing to order, if you don’t have enough information you can order the wrong stuff. This brought back lots of memories for me from my old job. I didn’t know how ever that the truck itself is sometimes mixing it for the first time in transit. I always thought they put it in the trucks already mixed and the trucks just kept it mixed until it was delivered.
I didn’t know the truck is sometimes mixing it for the first time in transit. I always thought they put it in the trucks already mixed and the trucks just kept it mixed until it was delivered so it didn’t set up. This was very interesting especially since I used to work in construction with my dad. I think your blog will help a lot of people decide what to order when they need concrete.
I see a lot of these cement mixers out driving around and I always thought if they were spinning it was to keep the cement mixed up not to do the actual mixing. I remember when the mixer (tear drop shaped thing) used to be on the trucks with the big end towards the cab, why did they change that on some trucks to be the small end towards the cab?
From what I have read and seen in videos on TV and cyberspace, these plants produce a type of concrete that is manufactured in a factory or batching plant, according to a set recipe, and then delivered to a work site, by truck mounted transit mixers . This results in a precise mixture, allowing specialty concrete mixtures to be developed and implemented on construction sites. This is important for the safety of everyone who will be inhabiting the finished buildings.
