What is Volumetric Batching 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. As the strength and durability of concrete is largely dependent on proportion of ingredients and water cement ratio, weigh batching is must and recommended in place of volumetric batching of concrete.

Concrete Mix Design Manual Rev08-19 - NCDOT
concrete divided by the weight of cement in the concrete. The water to cementitious ratio, W/Cm, is the weight of mix water in the concrete divided by the weight of the cementitious material, where the cementitious material is a combination of cement and pozzolans. The ratio is expressed as a decimal (example 0.446).
Batching, Mixing, Placing and Compaction of Concrete
