This will cause, less quantity of concrete per bag of cement. For example, if the bulking of sand is 10% and if mix ratio is 1:2:4, the actual volume of sand used will be 1.1 × 2 =2.2 instead of 2 per unit volume of cement. If this correction is not applied the actual dry sand in the concrete will be , instead of 2 per unit volume of cement.

The amount of bulking of the crushed material for older equipment models has historically been approximately 20 percent of the crushing depth. These older crushing machines will generally crush to a larger particle size and coarser gradation. The result is a higher bulking factor and more excess material which must be removed.

Also the resulting concrete will be honeycombed and its yield will be reduced, raising its cost of production. The volume to be increased can be calculated either by knowing this percentage of bulking as shown above or by bulking factor. If, V m = vol. of moist sand . V s = vol. of saturated sand . then bulking = [(V m – V s)/V s]

If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column. This formula only gives the ultimate load, but columns are design on safe load. In order to get safe load, divide ultimate load ( Load obtained from Rankin’s Formula) with factor of safety (F.O.S).

Hence, a correction factor for the bulking of sand has to be applied after determining the rate of bulking for the sand to be used in mortar and concrete making. As regards the rate of bulking of sand, it has been observed that it is related to two factors. (i) percentage of moisture content in the sand. (ii) gram-Size of the sand particles.
