If the volumetric batching is used for concreting, then the volume of sand is generally measured by boxes at site. If the bulking is found to be 20%, the volume of sand has to be increased by 20%. Suppose the size of box (measuring gauge/pharma) for sand is 30 cm x 40cm x 30cm depth. Therefore, volume of dry sand V2 = 36,000 cm3 (36 liters)
