A Concrete (Cement Mixer) is a machine that combines cement evenly to form aggregates such as sand or gravel and water to concrete. A typical concrete mixer using a rotating drum for mixing the components. For smaller volume works portable concrete mixers are regularly used for concrete, can be produced at the site, so that workers have enough time to use the concrete before it hardens time.
Special trucks for transporting concrete produced and ready-mix concrete to the construction site. They can be charged with dry materials and water, with the mixing occurring during transport. With this method, the material was mixed. The concrete truck transportation of liquid mixture maintained material by movement or rotation of the drum to the delivery.
