Besides, the out is determined by the mix design and the sequence of the dosing. The Volumetric Batching Plant. The volumetric batching plant used gates to measure the quantities.

Mixing and Transporting Concrete

Batching is the "process of weighing or volumetrically measuring and introducing into the mixer the ingredients for a batch of concrete" (Kosmatka, 94). Quality assurance, suitable arrangement of materials and equipment, and correct weighing of the materials are the essential steps that must be completed before any mixing takes place.

Concrete: Batching and Mixing | Concrete Technology

In case of continuous mixers, the proportion of materials is done on the basis of volume batching. Thus concrete obtained by the mixer has less strength than obtained from batch mixers. Further control on mixing of ingredients in continuous mixer is also difficult. These mixers are used on big concrete projects such as construction of dam etc.
