Methods of Batching Concrete - The Constructor

Methods of Batching Concrete 1. Volume Batching. In volume batching, materials are measured on the basis of volume. It is less precise method of batching; Measurement boxes or gauge boxes of known volume are used to measure materials. Cement is taken in the form of bags, where volume of one bag of cement (50 kg) is taken as 35 liters.

What is Volumetric Batching of Concrete?

Hence volumetric batching is not a preferable method for proportioning the ingredients of concrete. Volume batching of concrete may be allowed only where weigh batching is not practical and for unimportant concrete or for any small job.

Weigh Batching vs Volume Batching - GharPedia

The choice of batching method depends upon size of job, production rate and standards of batching performance. Traditionally batching is done by volume. Batching accuracy is important. It is however recommended to do weigh batching rather than volume batching. Volume batching may be allowed only where weigh batching is not practical.
