Three Methods Of Batching 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.
