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.

Example Using Absolute Volume Method

By using table 17-5 and interpolating between fineness moduli of 2.6 and 2.8, you find that for 3/4-inch aggregate having a fineness modulus of 2.7, the volume of dry-rodded aggregate per unit volume of concrete is 0.63. Therefore, the volume of coarse aggregate needed for 1 cubic yard of concrete is 0.63 x 27 = 17.01 cubic feet.
