batching concrete by volume

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.

What do you mean by Batching of Concrete?

Batching is the process in which the quantity or proportion of materials like cement, aggregates, water, etc. are measured on the basis of either weigh or volume to prepare the concrete mix. Proper Batching improves the workability of concrete by reducing the segregation or bleeding in concrete.

Concrete Mix Design Step by Step full Calculation

(Note 2: For pump able concrete or congested reinforcement in structure the coarse aggregate proportion may be reduced up to 10%) Hence, Volume of coarse aggregate per unit volume of total Volume of concrete = 0.62 x 90% = 0.558. Volume of fine aggregate in mix = 1 – 0.558 = 0.442. Step 6: Estimation of the mix Materials:
