1. Volume batching. 2. Weight batching. 1. Volume Batching: In this system of batching, the materials are measured by volume. The gauging of cement by volume is most inadvisable as it is difficult to secure accuracy in its measurement as the actual volume of a given weight of cement depends upon how it is filled into a gauge box and whether it is …

What is a Batching Plant? (The Ultimate Guide)
A batching plant is a piece of equipment used to mix concrete. It is typically made up of a hopper, a mixer, and a conveyor belt. The hopper is used to store the raw materials for concrete, such as sand, gravel, cement, and water. The mixer is used to combine the raw materials and mix them together until they form a homogeneous mixture.

Cement is consistently measured by weight, regardless of the batching method. The volume of a 50 kg bag of cement is 0.035 m3. A gauge box has a volume of 0.035 m3. Since the density of water is measured in kilogram per liter (kg/L) and water is measured in liters, the effect of fine aggregate bulking should be updated if volume batching is used.
