Concrete mixers are also sometimes called cement mixers and are basically a piece of machinery which is used to combine the ingredients needed to make concrete. These ingredients include sand, cement, some sort of aggregate like rocks or gravel in various degrees and water. The portable mixers are cylindrical drums which revolve to mix up the components which are loaded into the drum by hand.
Construction sites use this type of concrete mixers on-site giving them the opportunity to mix up small quantities of concrete which they can use before the mixture becomes hard and sets. If you don’t have a concrete mixer it is also possible to mix the combination by hand in a wheelbarrow or some sort of skip – this is okay for smaller quantities of concrete but is very labor intensive and very hard work.
Plants of concrete batching can provide larger quantities of concrete ready mixed for larger projects like road and bridge construction, large construction sites etc. The dried concrete mixture is combined at the concrete plant in the required quantities before being mixed with water in the concrete truck as it transports the materials to the building site. This not only cuts back on the manual labor involved to produce the concrete for the building project but it is also a much more accurate method of creating the right type of concrete for the job.
The durability and strength of the concrete varies according to the mixture of the ingredients used and the ratio of water added to the mix. This can be computer controlled at a modern concrete plant which ensures that the mixture is perfect for the job required. Although experienced builders may be able to judge the right consistency for concrete, manually producing it on-site is a much less accurate method of creating the right type of concrete.
