  • VOLUME BATCHING OF CONCRETE – THEORY & EXAMPLE CALCULATION

    Jun 17, 2016 · The top of the materials should be struck off level with a straight edge. The ratio of materials of concrete decides the capacity of the box. Generally capacity of a gauge box is equal to the volume of one bag of cement (i.e. 35 litres). Convenient sizes of gauge boxes to suit different proportions are given in the table below.

  • Bulking of Sand & Why is it Important in Construction

    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)
