Difference between weigh batching & volume batching - Civil4M

Say you want to make concrete of 1:2:4 via volume batching Then you will take 1 farma cement then 2 farma crush sand and 4 farma 20mm. Will do add water as per proportion, and concrete is produced. The above method is simply name as Volume batching. Weight Batching Here instead of volume, ingredients are taken as per weight.

Batching and Mixing. Batching-- Batching of aggregates and cement should always be done by weight. Other components, like water and admixtures, can be batched by volume. Batching by weight allows rapid and convenient adjustment of mix parameters if desired. Material quantities should be measured with a high degree of accuracy.

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.

How to Make Concrete – Batching, Mixing, Transporting

Volume batching of concrete is a too accurate method for making concrete because of the difficulty it offers to measure granular material in terms of volume. It is a fact that moist sand volume in a loose condition weighs much less than the same volume of dry compacted sand.
