Mixing and Dosing
Introduction
Concrete or concrete plant is a facility used to manufacture concrete or concrete from the raw material that composes it: aggregate (sand and gravel), cement and water (it may also include other components such as filler, reinforcing fibers or additives). These components, which are previously stored in the concrete plant, are dosed in the appropriate proportions, to be mixed in the case of mixing plants or directly unloaded into a concrete mixer truck in the case of batching plants.

La planta de concreto u hormigón se puede clasificar desde varios puntos de vista:.
Depending on the type of concrete or concrete that is produced
- Mixing plants: for the production of concrete or mixed concrete.[1] They include a mixer, which is responsible for homogenizing the concrete or concrete mixture.
- Batching plants: for the production of dosed concrete, sometimes called dry concrete. The main characteristic of these plants is that they lack a mixer. The mixture of dosed components is poured into a concrete mixer truck that is responsible for homogenizing the mixture.
- Cement gravel plants: for the production of a semi-dry mixture of gravel with cement. Normally, these types of plants carry out the dosing and weighing of the components in continuous mode.
- Combined plants: for the production of mixed and dosed concrete in the same plant, through the use of a by-pass system, which causes the concrete to pass through the mixer or be directly unloaded into the concrete mixer truck.
Depending on the mobility of the plant
- Fixed plants: are facilities intended for a production center with a fixed location. The plant structure is designed and installed with the idea of not being moved throughout the useful life of the facility.
